Hi all,

Apologies in advance for the very lengthy story ...
I met this guy (D) two years ago through my work. I live in Belgium and he lives and works in the UK. I work in an international NGO and the company for which he works is amongst our members. So now and then we get to meet. Since our first encounter, he has been very kind to me. Shortly after that first encounter, I helped him fix some hotel bookings for a meeting we were organizing and that he was going to attend. The meeting was a huge 3 day bash in Liechtenstein.On site, at one of the side meetings a guy who hadn't registered for it sort of roughhoused me and D came to the rescue . At that time, I had just been hired after 3 months as a temp and my boss was somewhat snooty with me. D witnessed him snapping his fingers at me during a coffee break and D had been previously told by one of my senior colleagues( who had befriended me since day 1 and who's nickname is Charlie aka "Charlie's angels") that my boss was sort of mobbing me ... so D came to me and asked how could I stand being snapped at? I told him in a jokey tone that my boss was so stressed out he was having hallucinations and was mistaking me for Jeeves ( famous butler character in PG Wodehouse's book)... D burst into laughter and asked how the hell I knew who Jeeves was ...And that's how the story began... during the rest of the 3 days of conferences and evening bashes, he would now and then come to me to start a conversation ... For instance: I was standing almost in front of the chart where all the airport shuttles were stated and he would ask me where the chart was ...and after that asking my help to locate his own schedule.... and so on so forth...We parted in a very friendly way and that was that for 2010 and in fact at the time, I just thought he was kind and very handsome, but not much more as I had just called it quits with my son's father ... and I didn't feel in the mood for flirt at all!
In 2011, we were going to Istanbul and he phoned me again to seek my assistance for hotel bookings, which I gladly gave :-). On site, there was some sort of evolution. I was bumping into him a lot... so much that it didn't look like a coincidence anymore. Every now and then, when I was popping of of our "on site office" bam, I bumped into D who also took the opportunity to make some small talk.... Okay, he needed to pass in front of our office to get to his room but ... :-) If I was carrying something heavy, he would insist on helping me , did I go upstairs by foot, he would follow suite... and even once in the lift, he sort of started flirting... The thing is I have a necklace with a key ( symbol of the hotel concierges:I worked for 7 years as a front desk clerk in a 4**** hotel) and so, when we were alone in the lift, he was intently looking at my necklace and said" very nice key you have there , I wonder where it leads to...", I answered him some gibberish about the key but didn't reply directly to his question. Instead, I asked had he shaved his beard... To which he said: "yep, this morning, do I look any younger ? ( D is 13 years my senior) ... Well, at the time, again , I didn't take any hints ... although I found him very attractive and kind... He was just so above my league (hierarchy wise and also experience, education...)... Arrives 2012 and another big bash is scheduled for April in Belgrade. During the planning stage, I notice there is a cock up in his colleague's flight plan and so I very diplomatically mail his colleague with him in copy. Ensued an incredibly long string of mails where each time he was in cc for info , he answered me ...like he wanted to get the conversation going on... and my, oh , my was I happy to see his mails popping in my inbox! April arrives and I go to Belgrade to be onsite...On the day 0 of the big 3 day bash, shortly after arriving at the hotel, guess who pops up in our "office" , casually enquiring if I was done with my work and was I going to attend the welcome cocktail... At my arrival at the cocktail I get the hint from my very good pal "Charlie" that my arrival had had a tangible effect on D who is tentatively making a beeline towards me in what is supposed to be a nonchalant manner... He tried to start a conversation with me in a casual way but I was so shy all over sudden that I cut the conversation short... later on he eventually caught up with me and we chatted for a bit, the rest of our stay there, I will spare you as it was on the same flirty tone... With D teasing me or paying me compliments ... Upon departure , we said, see you next time with a deadline for a huge conference in Qatar in October, then he said, maybe earlier, sweet wishful thinking .... on both our parts I have to say. Turns out he had to attend a meeting I was organizing for a Committee in Brussels. He had a problem with registering which I fixed and he sent me a short but very nice mail with the others concerned in CC it said: "L, Your'e a star it's Official!". When I saw that email and the ones that followed I was besides myself. He and my two other contacts were taking turns complimenting me ... for things I deem absolutely normal. That day, I befriended him on FB as earlier in Belgrade, he had sort of tried to know whether I was on FB , then, again, I didn't take the hint either ... Within, minutes, he accepted my request and from that day onwards we were communicating now and then via FB. Well, mostly him to begin with... I didn't want to appear too clingy ...then progressively , I also commented on his posts. One day, I posted I was going to go to London and his reaction was really speedy... he immediately proposed a drink ... Which onsite became drinks+supper+stroll along the Thames... seasoned with dollops of compliments on both sides. I had already fallen hard for him, but did my best not show it too much. He was going off on holidays the day after with friends . There , with his gang of dudes, they apparently met some gals and one fell for him. So hard, she is all over him like a rash. Posting things on his wall, left, right and center ... Putting a photo of them both as her profile pic(last week or so) , (when he didn't change anything relevant in his info), 2 weeks ago, I commented on one of his shares because it was unavailable outside the UK, so I was saying , "arrgh too bad" His reaction startled me as I wasn't expecting any reaction on that silly post of mine :-) " Well, There is 1 way to solve that problem:-)" Meaning I guess: "come to London"... I answered a bit too noncommittally as I didn't want him to think I was all over him like the other woman. The he started posting all the gold medal stamps RMG was producing for TeamGB.... In the meantime, we communicated a good deal last weekend and he even thought about my birthday. Last weekend , I received a postcard from him at my home adress. Concluding with "lots of love" when he never ever signed like that before... Just xx . When I thanked him in a FB private message ending with lots of love too , the conclusion of his answer was "I'm glad the card hit home. How sweet... :-). Means he is happy that I answered lots of love too ? guys please help me grasp the bigger picture, I feel like I'm in love with a riddle, an extremely kind and handsome riddle, but a riddle all the same ... Or is it our respective jobs ? or is it the age gap, he is worrying about ... , or am I pushing him away without doing it on purpose... Oh, BTW, when I logged in on FB to thank him, I noticed his groupie had changed her profile pic again and he wasn't in the picture anymore, when he was still in the pic24 hours before? Coincidence?

Am at loss and I really do love him to bits even if I try to appear as cool as a cucumber :-) out of fear of rejection...
By the way, i'm a Leo girl and he's a Libra guy. I'm not in all that astrology thing on a day to day predictions basis but I already noticed you could find some personality similarities in persons who were born at the same period of the year.

Please help me! Advice is strongly needed here
