Hi, essaie, welcome to PsychCentral (PC).

It's hard to let go of anyone/thing, especially if they're familiar and what we think or thought we wanted at one time. How is it you have a new boyfriend if you're not willing to be over Kevin? I remember breaking up and it was my new boyfriend (now my husband) who got me "over" my old boyfriend.

I would spend more time with myself and getting to know myself and what I actually want. If you didn't want to sleep with Kevin, I don't see that he's been a very good boyfriend to you, hasn't done you any "good"? What is the attraction there?

Think of the future as an adventure. You're going to spend the rest of your life there, you can't really go back. And it sounds like if Kevin is constantly breaking up with you, why would this time be different? It sounds like Kevin isn't very mature and being with him is not helping you any. I would figure out what you actually want and go for it in the future and let Kevin chase you (which I doubt he will) instead of you chasing him.
