I don't know. I don't think so, although it does make him look bad... I'm nowhere close to being a lawyer, I just know of a woman my mother used to work with who walked out of the house, and because of that she was cited with abandonment. (I believe he had an affair, although don't know the gritty details.)
Well, to be honest, the first go round I just got mad. And it had only been a few weeks. I got tired of his whiny back and forth "I love you, but this isn't working." (He didn't even give me the ILYBNILY line....sheesh...) I felt yanked around, and we just had this huge blow up fight...and I walked out the door. He had already forced me to sign him off of the lease on the apartment, so it was mine, and I wasn't worried about that. I only went back for the dog. (And I think the fact that I took her really scared him.) That was when he was deep in the EA/brief PA.
Anyway, three days and that was it. He actually called my cell every 20 minutes for over 24 hours. No joke. He even showed up at my job. The man was in complete tears, hadn't slept for two days, when I went back.
I honestly think we only seperated a second time because neither of us dealt with the issues from the first go round properly. It was completely different than the first time.
Anyway...it wouldn't have worked the second time with H. I ignored him for two weeks after he kicked me out of the apartment. (Only in his name. Long story.) And then I found DB.
However...I wonder if some version of the LRT might work for you? Seems to bugger him out. Notice he freaks when he doesn't know where you've been?
