I can't even come close to hitting the nail on the head as Train has and I'm a guy, but here's my 2 cents.

I'm separated too, and WAW and I haven't crossed that field you and husband are in that you mentioned. However, WAW still comes over and acts as if this is still home and lets me come over to hers (I choose) to visit with the kids and help out.
I'm replying only because today I was talking with a female coworker who I've been talking with about my sitch. So in essence this is coming from another female, but she primarily said, "She wants something."

So, your husband wants something and in my opinion he doesn't FULLY want the marriage just yet. My WAW too, has mentioned she is sorry a couple of times before we separated, but here we are 4 weeks separated (she wanted to separate) and I've since put myself out there at least 3 times expressing/acting on my feelings only for her not to reciprocate those same feelings.
