I don't really need advice with this, as it is clear what his motivations were, I just need to unload.
So, when I was 22 I met the love of my life. We were together for 7 years and had a wonderful relationship. He was loyal, sweet, kind, funny, attractive, smart, considerate, basically everything someone could want in partner. We lived together for 5 of the seven years and when he was accepted into a grad program in a neighboring state I quit my job and moved to be with him. After living there six months I came home from work one night and he told me that he no longer loved me. He would not give any reason other than that he had fallen out of love. He said I could stay there as long as I need while I looked for a new place, but that we would be sleeping in separate rooms.
I was devestated. After sobbing all night, I packed up my things the next morning and moved back to my home town. That was 6 years ago.
Around Thanksgiving I received an email from him. It was general, asking about what I was doing, my family, etc. I replied and learned that he had moved back to where I lived. We agreed to go out for dinner. Upon meeting, it was like we'd never been apart. We laughed, talked, and had a wonderful evening. I didn't know if he just wanted to be friends, or if he was interested in dating again. Stupidly, I was scared to bring up our breakup, how he'd hurt me, or what he wanted now.
We ended up hanging out in a friendly manner somewhat regularly, and I guessed that he just wanted to keep things platonic. Though I was sad, I was willing to accept this as I enjoyed his company.
This past Friday I went over to his house for dinner. We were both sober and clearheaded and he began kissing me. We ended up sleeping together. Afterwards, there was still no discussion of where this was headed. Saturday morning I left. He seemed cold and withdrawn that morning and didn't even walk me to the door.
Then....nothing. I have not heard from him since. Not a call, not a text, not an email. Nothing. He broke my heart all over again. Pathetically, I looked at his facebook page and read the flirty messages he has started leaving for an attractive woman 10 years younger than me. I can't even be angry with him. I knew what he was capable of, and came back to be hurt again.
