We're supposed to be divorce busters here, not trying to talk people out of their marriages. First of all LL, I'll admit it, men just don't get it! I already explained the "gunk" in his undies to you, so I won't go into that here. I know your H works hard, and he probably is tired at night. He just doesn't understand your needs (a man thing)!
But when he had his A before, he wanted a D, right? And he moved out! This time, it's only your suspicions! You need to put those behind you. At least he's home every night. LM123 hit the nail right on the head! Reconciliation is tough, VERY tough! I still think if I had been more patient with my W, I may still be M.
Let's look at the good side of things. Your H is a good provider. He's a good father. Has he brought up D again? Make a list of the 10 best things about him... ( )! Then forget ALL the bad things! Did you ever think you're expecting too much?????? (Before all you other posters pick on me, LL and I go back a long way, so I can be blunt with her)
I've learned more about women the last 3 years, than I did the whole 31 years with my W, mostly from this board. Men are simple, and women are complicated! This time, you should give him the benefit of the doubt! Part of the WAW syndrome is the woman finally gives up in her M. When she gives up, and resigns herself to a D, she stops all the bitching and complaining. At that point the H thinks the W has finally "got it", and everything is all right!
