I think Thin4good said it all. I'm sorry you had to go through this cr*p. I had a best friend (without benefits) for over 8 yrs before we "got together". We moved in together after 6 months of dating and got engaged 6 months after that. One day I came home from work (at my usual time) and found him on the couch with a 16 yr old girl (he was 26). Disgusting, not to mention illegal. He appologized and cried and all that crap and I took him back. Then I found out he was txting a 18 yr old girl (at least she was legal) constantly and I told him after what happened (and I hated to do this) that he had to promise to stop talking other girls completely for me to stay. He did, then I found out the next month (when the phone bill came in) that he never stopped and then he lied about it when I confronted him. I left him and yet still had a few instances while we were in the "still trying to be friends" stage where I broke weak and slept with him. It was comforting at the time, but I look back on those instances now with regret that I was so weak. (not saying you are, this is just my story) I still think about him sometimes and miss him, but I KNOW I'm better off keeping him in the past.
He's actually one of the people I can't wait to "run in to" up town once I lose more weight b'c when we got together AND broke up, I was big, and I would really like to rub it in his face. (not literally ) Oh, and an update... four years ago I saw him at my brothers graduation (he was there to watch his new girlfriend graduate... HIGH school!!). I was with my bf (now hubby) and he caught me on my way to bathroom and made a not nice comment on my bf and I said, "at least he doesn't have pedifile (sp) fetishes!" lol... The girl I had originally caught him with dropped out of HS, married his best friend after getting prego with his kid, and both are unemployeed. He is currently living with his parents AGAIN (he's now 30) and the last time I heard, he was back at his old sh*tty job. Life is so fair sometimes!!!
