Healing and moving on

Even tho my wife had made the move to suggest splitting...the relationship has been dead for so long. In the beggining it was good...all the way till we got married and she told me a little secret, that she had slept with other people while we were dating. That hit me like a ton of bricks and i dont think i ever did get over that. She went into a pretty bad depression that caused some suicide attempts, was cutting, her anxiety turned into agoraphobia...all that over 3 years. I think that's what did it for me I had such resentment because of the way she made me feel, the extra work I had to put in to keep HER going. Over the last year, she's working, no depression...has been faithfull...but I' feel out of love with her and was not happy. We went through the motions and such but thats all it was...the motions..someone was going to have to break it off eventually and that time is now. I know this is for the best, the guy she is seeing works at her work, apparently a really nice guy and makes her feel like a princess....and makes her feel..happy. Which is what i want. The lust in our relationship is gone, i still care for her as a person..like a friend or a sister....so why does thinking about him and her together just make me sick? Maybe its a "She mine!" caveman deal? arg! And im so nervous about meeting new women, I havent been in "the game" for 7 years, I know im only 23 but how do i start over? How do i start a new relationship...Im lost!!..halp!!..lol Anyway, i felt like i really needed to write this down..Last night we spoke for hours about the last year and how she was trying to make me happy...and nothing was good enough, and it's very true, nothing was good enough because there was no love left for her. Ok so, I need to meet new woman, get myself out there again...were to begin...........
