Trusting I have been reading for months now, but your thread is the first one I have wanted to reply to. So please bear with me. Who knows, maybe I will post my sitch someday.
My H and I are also living in the same house. I have been in our master bedroom, and he has been in the guest room for a year now. He is in MLC and has memorized the script well. It is so hard watching him come and go, wondering where he is, and who he's with. Sometimes I think it would be so much easier if he wasn't living here. What I have the most trouble with is when he comes home right after work, for two nights in a row ( we eat dinner and watch a movie together ) and then the third night he comes home, changes his clothes and is gone for several hours. When he comes home, he barely says anything to me, and goes straight to his room.
I don't want to hijack your thread, so I won't go into anything more here. I just wanted to let you know that there is someone else out here that is still living with their MLC'r.
