It just sounds to me like you two need couples counseling. One of the big things couples have trouble with is communication and trust --and counseling can help immensely with both those issues. How about giving that a try? It sure can't hurt. And if at the end of the counseling, you two still can't make it work, you at least have given it a GOOD try and will have no regrets.

I wish you the best of luck. I hope things work out. God bless! Hugs, Lee
