girl troubles

[xxGreat1xx]

Ok so I'm 20 years old and I have been in a relationship for almost two years now. We met when we were freshmen in college now we are juniors. For the first year or so she was real laid back and didnt really care too much what I did, I wasnt doing anything bad but she just seemed to trust me more hanging out with my friends and stuff. But as of the last few months in a twisted bit of logic she questions everything I do. We have had a few major fights and near breakups.

Last week I decided that I just didn't care if we broke up. I am hating being tied down, it's just not my style. It's why I moved out of my parents house as soon as I turned 18. But, tonight we were just sitting around and we got in a small argument about something(that tells you how small) and she says, "why are we fighting all the time now?" I tell her I dont know, although I assume I have probably been acting different because of my recent change of heart, and she has probably caught on.

Long story I know, sorry. So we had a very awkward night after that and she didn't say much and now I think we both know how close we are to breaking up. But even though this is what I thought I wanted, I feel horrible seeing her hurt and I'm wondering if I might be making a mistake. I have lots of other stuff to fall back on that I don't get to participate in with a girlfriend though, a fraternity, road trips, poker at the casino, ect.

I dont really know what I'm asking anyone for, maybe just someone in a similar situation or someone who had a similar thing happen and can say how it worked out. I mean, she has freaked me out a little talking about getting married and what she wants to name our kids and all kinds of stuff. I think I am definitely too young for this stuff. I guess I just needed to vent. Replies appreciated though
