A lot of rambling, sorry!
Recently around the end of March I broke up with my boyfriend [I'll call him A] of 2 years. We were just sort of losing contact and bickering often about small things and since he's in his 2nd year of college and I'm a junior in highschool we don't really have time to talk to each other except through MSN. We don't hate each other or anything, but we decided we would take a break and he gave me the decision of whether or not we should get back together, but I know he really wants to get back together. Honestly, these past weeks without him have felt pretty normal because we rarely see each other anyway. I guess I still miss him once in a while, though. He was the only person I've ever had such strong feelings for.
What is clear is that you don't seem to like to be alone, to the point where you are ready to backtrack into trying things that you already know didn't work in the past. And that is a pity, because you condemn yourself to a mediocre romantic life.
I wouldn't consider a two year relationship with A to be a lukewarm one. Plus I know plenty of people who redate past boy/girlfriends that end up fine.
