((((Maple)))) Sometimes there are no words for the intensity of emotion you can feel at a time like this. It is too much. We are all fortunate that we have each other here... we understand. Somehow that just helps to not feel so alone.
I am glad you are getting legal advice. It sounds like it is important given some of your H's actions.
Focus on self care right now. This is a very hard point in your sitch. After confronting my H, he "waffled" for three more weeks. He now says that my behavior during those three weeks (180's, "acting as if", making myself the better option, not pressuring but yet keeping firm boundaries) were some of the things that caused him to re-consider our M.
Are you getting any counseling for yourself? That helped me tremendously too.
Take care. You have been amazingly strong so far.... you can do this!
