I happen to remember an old poster whose husband acted similarly after they separated. It CAN be a sign that a MLC is at hand, but there would have to be many other "signs" before you should make that assumption. And actually, you said "has anyone else's done this after their MLC"...so I would ask you what makes you think it was over in the first place, if that is indeed what your H is going through?

As for you not feeling he is attractive right now, that's not so bad I don't think. A lot of spouses act in ways that are unattractive so this would be along the same lines I think. Besides, did you just love his previous "look" or do you really love the man?

I am concerned about your "bi curious" remark.
Is it his style of dress that makes you think he's leaning that way?
I didn't realize there was a certain fashion trend out there that suggests a person swings both ways.

We'd need a lot more information before we could really understand and help you.
