Kool-Aid

I wanna explain this situation and I want some inputs.

I was just in a relationship for a year and three months. This guy, now I see, treated me far from my worth...I mean like shit...but I held on, as a good woman, giving him the benefit of the doubt. I got a card for my B-Day, the sex wasn't really all that good because he seemed to have not cared "for mine" as much as he did his,he even left me at a party drunk. We had broken up and gotten back together twice because I would check him about how he's acting in the relationship and how I was unhappy...
The day before I left to come to Iraq I asked him 3 times if he still wanted to be with me and if he still wanted to wait for me....every time...he said YES. I finally arrived here thinking that my man would be by my side through this since I waited 5 months for him when he was here...and three weeks of me being here...he breaks up with me on email.
So it has been a month and Im ok...until I get a message from a mutual friend of ours saying that he's got a new girlfriend.
Wow.
