I'm sorry you're having to go through this. When reading about your sitch it sounded like it was me writing it. My H did the withdrawl of OW, the moping, telling me he missed her, missing for hours at a time to "clear his head." Beleive me, I didn't want to be a detective either, but I just didn't want to stand around waiting for him to come home.
My advice would be to set boundaries for yourself or the WAS will feel they can walk all over the LBS. I believe I was too nice to H, I didn't set any boundaries, I allowed him to come home when he wanted, leave for days at a time without questions. I myself feel that I let H walk all over me and lose any respect he had for me. I don't know if that's the case, but that's how I feel.
My H filed for divorce yesterday, but I'm okay with it. I have accepted it and I'm moving on. I know that I tried my hardest and he admitted that he did not try to work on our M. I know that I have come out the better person from H's A.
Keep your chin up!! I'm sure things will get better. GAL and set some boundaries with H.
