I left my daughter at her mother's and when i Said bye she was so Sad and asked me: "why do you have to Go?" It hurts so much. To top it all my wife has been treating me like a stranger. She Just opened without saying nothing and when i left she Just Said "bye". Not seeing her again would help great deal but because we have a daughter we have to keep seeing each other which is a complete torture for me. It is so hard to love someone and have them feel nothing for you anymore. And my wife is beautiful, i bet pretty soon she'll be with some of those gym rats where she works as a personal trainer and i'll feel even worse. I am so hurt and afraid i will do something to myself. I Just can't stop thinking of dying. It would be such a relief to get rid of everything, all the pain, all the noises in my Head, this crushing weight on my chest, this love i feel for her that won't let go of me.
I hope those suicidal thoughts have passed now -- PLEASE DO NOT do that. Think of your daughter having to grow up without you to guide her and only be brought up by your cheating wife.
I hate to say this but she has most likely already BEEN cheating on you again. You both never resolved the first infidelity.
YOU did not lose your family -- SHE is the one driving you away.
So, get your plans together for YOURSELF and your daughter. Don't worry about her, don't talk with her unless it is strictly about the divorce or your child, do NOT discuss your feelings with her.
Work on you -- eat, sleep, exercise, improve YOU, improve your relationship with your daughter.
Ignore her when she wants to hang with you or needs your help. Just tell her that her new BF can take care of that for you and walk away.
EDT:
Sorry just caught up and found out that she HAD cheated on you again. Move on, get your lawyer on the case, and the above mentioned items are still valid. You will be MUCH better off without her and her manipulations.
