GTO, just read your latest posts. I think the way you are interacting with your H suggests animosity. I know, who could blame you, right? But I bet you when he leaves, he leaves either angry or feeling bad about himself, which will not help the M at all. If he asks, it's ok to share where you are going. You could've said you took down the pictures because it felt right to you given the way things are. Basically, show that you are happy without him but don't show that you are just waiting for him to file and that you think he's Mr. Despicable (even if he has behaved like that.) Treat him like a normal person, not with contempt or reproach. That's my advice to you.
It's too soon for you to contemplate being w someone else. For me too. Focus on loving yourself for now. The texting is harmless. I would not worry about it. But don't get yourself anxious about who's next. Focus on today.
