So my ex girlfriend and I went out for about a year and a half, and it was probably the best experience of my life. We shared so many romantic and fun times together, shared so many interests and I could tell we were meant to fall in love with each other. However we had some issues just like any other couple, I caught her talking to her ex a couple times but she swore to me that it was nothing and I believed her because she was never dishonest to me. She also caught me texting this girl (who was a mutual friend for both of us, but she professed her love to me in a drunken rant one night and my ex asked me not to talk to her again). This same girl texted me again the other month and asked me how I was doing and I responded great. Then my girlfriend found out about that and confronted me about it and I told her I'm so sorry that I lied to you about it and that I talked to her again. She seemed to forgive me and everything seemed OK for a couple days, we had great dinners, we made love, and cuddled like always. However one day she came over and said that she really didn't want to break up with me but she felt she had no other choice. I told her please don't I will do absolutely anything to keep you in my life. She said OK I just need time to think I love you and kissed me and left. I then texted a mutual friend a day later and that friend said I'm sorry about the break up and I was like, we didn't break up... did we? So I texted my ex and she was like yeah I thought I was clear about the whole situation, I want to break up with you. So it hit me very unexpectedly. Anyway, its been about 3 weeks and about a week or two ago I found out she was talking to her exthat she was talking to during out relationship. And once I confronted her about that she blocked me on face book twitter etc. I understood that, but I still don't understand why she would block me out of her life with such ease. I want her to feel this pain that I'm feeling of "what does he have that i dont" (her ex treated her very badly, calling her names, constantly making her cry, also doesn't fir in with her crowd.) She told me she won't get over me for a very long time and she said we might get back together at some point. But now she's already with another guy and probably happy as can be. We have literally rhe same mutual friends so I do not know how I am going to handle going to parties, get togethers etc. without getting extremely upset. I need some sort of help with this, will she ever feel regret like I do? Will she ever feel as bad as I do? Or is it true that nice guys really do finnish last? Thanks in advance guys!

Don't worry about what she may or may not feel, just do what you need to do to move on and get over her.
If you two have mutual friends tell them not to talk to you about her. Stay away from places you may see her for a while. It will take time but you will get over her.

Yea, its hard to avoid her sometimes because we go to the same college so I end up bumping in to her sometimes. Just the fact that she is treating me like I meant nothing to her is what really gets me. If she would have said like our time was great but we both need to move on or something then I would feel so much better about myself. Its not even that I'm sad, I'm more along the lines of pissed off...

Well you'll get past this. Who knows why she is behaving as she is. Don't get yourself in a rut trying to figure it out

Yeah, it just really bothers me that she got back with her ex who literally called her every name in the book, and she complained about him to a lot of people. I just wish she wouldn't think of me as an a-hole ex who treated her badly because I most certainly am not. Even though my friends agree with me (who are also her friends) they will not tell her the mistake she is making. I wish they would, just because I want to see her happy.
