Good grief. You're never really alone, are you. I was suffering through this tonight, and then I clicked on the forum and saw your post. My wife (of 25 years - but it's a long story) and I are, now, basically room mates. She went to look after her mother for a month or two, and it ended up being years. Then she came back home, and I was eager to get back together, only to find she's a different person. Perhaps *I'm* a different person, I don't know. But we're back together with..... well, a room mate mentality. We don't sleep together, I don't see much of her during the day (she lives in the bedroom) and we don't seem able to have a conversation, let along intimacy.
At first I was willing to try and figure out what worked for her, but increasingly I find myself withdrawing and holding on to my own needs and wants. We're just not jiving at all. What the hell happened?!?!? Living Apart Together completely describes it. I'd never ask her to leave. She can't ask me to leave (it's my place), but I just don't feel an emotional connection any longer, and don't see the point of our being together.
Divorce? I don't feel a desire for that. But I'm getting nothing from this at all. Answers? No idea............
