It's definitely a dealbreaker if they've resumed the affair.
I'm undecided if it's a dealbreaker if he's just not moving fast enough for me. As I've said, it's been back and forth with him since day one. I'm not sure how much longer I can stand it and as more time passes I keep thinking that it's becoming less and less likely that he's going to fully turn.
OK fair enough. But think long and hard on this, because from where I'm sitting it's highly likely that he's in the second scenario up there, as much as you're frantically worrying that he's in the first. ^^
