First I can empathize with your feelings right now, but I totally agree with NOPS, backoff. Right now, because you are so upset, you are your own worst enemy.
Give us more detail please as to your R with your H. There is something going on in your M that needs to be addressed....your H saying "everything has changed" isn't an answer, it's too general. In my experience, when my H would give me answers like that...it was his way of giving me an answer without answering the question at all....his way of not dealing with what he didn't want deal with.
You two just have some issues to work past. There are many people here who understand your situation and can help guide you.
