I really don’t know how to say this, but I love someone but I am not ready to settle down.

Me and my ex broke up 6 months ago, she was really heart broken and it was killing me to see her that way and because I was the cause of it. I still stayed by her side til now trying my best to cushion the fall, make her get over me, and make her happy as possible. I think I really inspired this girl to do better in life while we were together or something, she went from drinking/partying all the time to doing sooo much better in life, like college, job, and etc… If I leave, I’m scared she’s going back to those party/drinking/loser life.

It’s not my problem but I don’t know how to explain it, I want to see her as happy as possible with a really good future but I can’t be the reason for it, at least not yet. I am only 23, I love her but I am not completely ready to give my whole life to her. I still want to see other people and experience new things and stuff… or I know that I will regret it on my 30’s, 40’s that I spent my 20’s already being so serious.

She said If I ever do anything with another girl like even take her on a date, she will completely walk out of my life. That really made me mad because it’s as if my freedom is completely gone ever after we broken up, so we decided we’ll completely walk out of each other life. Then I started crying non stop for hours and hours but I was going to be okay with it sooner or later. However, The next day she was still crying, she called me and said “I’m not ready to walkout yet”, and so we’re still together as “friends/lovers?” whatever you want call it.

I really don’t know what to do… I want to see other people and enjoy my 20’s and I don’t want my freedom completely taken away yet, but at the same time, I really care about her future and happiness.
I know I have to choose but what would you guys do?
