What am I supposed to do?
About 2 months ago I broke up with my first serious girlfriend (of 10 months). She said she loved me, that she would love me forever and I it was said by others that she was crazy about me. (For some stupid reason I am insecure about my relationships with people, not just girlfriends but with others too, but that is beside the point). Well, we started dating in the middle of our senior year of high school, she was the one who initiated the relationship in the first place, too. If it helps to know this, she spent A LOT of time at my house, she would sometimes stay until almost midnight on school nights (I think this was because of family issues).
I wasn't expecting this: about three months into the relationship she said "I love you" for the first time which I wasn't ready to say back until like 1.5 months later. We were joined at the hip, however, we both knew that college was coming like a freight train and we were going to schools that are more than 10 hours apart by car. We told each other we were willing to try long distance. Now, we are both ones to party which does not help anything much. About 5-6 weeks in, things got a little shaky; I have to admit some of it is my fault because of my insecurity about relationships, and I made her believe that I didn't trust her at all (which probably is true to some extent).
The week before her fall break starts (which she was coming home for to see me) we began to fight/argue about the status of our relationship. She was very mad at me and because of only 2-3 days of fighting we had basically broken up. When she came home that weekend I also drove back up home to see her and the purpose of this meeting was simply to end things. This is where I am confused/frustrated/pissed off: She revealed to me that she had, that week, cheated on me because we were fighting. Is her problem? She said to me: I hope we can be friends and she even said "I love you" again before driving home. About two weeks later I log onto Facebook to see that she has already entered a relationship with this new guy (I really hate this guy) and she seems so damn happy where she is. That is what makes me really upset, how could she drop me so easily and just move on like that?
Another thing: the guy she is apparently so in love with ALREADY is a senior in college... what is she thinking?
The most important issue at hand for me is my current situation. Because we have the same group of friends, we are having a get together of this group of friends the day after thanksgiving and she is going to be there. She texted (first contact in 2 months) me several days ago basically saying I don't want to make it weird for our friends because of our situation. She also said that "hopefully we can be friends" but I am so made at her that I don't see how that is even possible. She also told me that if I want to talk that she is always "here for me" but I just can't get the feeling out that she is just spitting BS into my face. Anyway, she sent me this text several days ago but I never responded... I did it to get a message across that I don't even want to see her, but I am going to see her at my friends house in just a day.
I have no idea what to do/say, and I don't even know how she really feels about all this; one part of me says maybe she is sincere, but the other half of me thinks she was just using me and couldn't care less about what happened. It has been tearing me up all semester and I feel like doomsday is coming.
My question for all of you is: What am I supposed to say to her? I feel like I shouldn't have to reach out to her (that if she really wants to be "friends" then she should be the one to initiate) but she is so damn blind and it appears that she doesn't care about the situation at all which is the most confusing thing I have ever come across in my life.
