Bamagirl, Welcome to the boards. One thing that struck me in your sitch is that you said your H was depressed after he came back home this last time.
Well fast forward He moved back in 2 weeks ago and she is still caling him and he is so depressed and back to treating me just like he did before he moved out 1 1/2 yrs ago
I don't know about the treating you badly part, but he should be depressed if he has truly given up the R with the OW. They have to go through a period of mourning as they are experiencing a "loss". As painful as it is for the LBS, the WAS need to make this transition. He is probably taking his miserable feelings out on you. Just know that he should be feeling badly. If you see no depression or mourning, my experience has painfully taught me that the R with the OW is NOT over. Your H probably expected to waltz back into his old life. Neither one of you can do that. He has to go through his process and then the two of you can rebuild and start to work on the issues that caused the A to happen in the first place. I recommend that you get "Private Lies" by Frank Pittman and others have recommended "Surviving Infidelity".
I think both of you may have had unrealistic expectations on putting your M back together. Slow down. Take a few deep breaths and start over.
I wish you well. Come back often for there are lots of good people here.
