JKS, I've had the "confused" H for a year now but finally pushed him off his fence. My H had the affair first...and just now moved out. I agree with some of the other responses that "confusion" can just be an excuse for them to try to maintain both lives as long as possible.
Being on the fence also doesn't mean they are ML to both parties. In my situation, H was keeping me emotionally invested enough so that he could continue to come home and have a facade of a family.
I loved your 4th of July post and I think you saw a glimmer or how life can be okay (even great!) without your H. Reading about you fainting was horrible...and a sign you CANNOT continue to deal with him and this situation.
I think you should detach from him and consider filing (or at least tell him you are considering it). His behavior may get "uglier" because he won't be happy you are forcing the issue. But, I don't think you should go on like this.
If he eventually wakes up, you can consider getting back together with him then...and I bet he will come around as you GAL and make yourself a better person. But, you deserve better now!
