welcome to soberrecovery, strongenuf.
as you can see, this is a very supportive site. please keep hanging out here!
my two cents is to contact a family law attorney. the first consultation does not commit you to anything, and does not cost you anything.
the more you start finding out what you're up against instead of speculating, the better off you will be. and you will also get more courage.
ya know, maybe your husband is placating you, maybe he's manipulating (or trying) you, or maybe he is truly remorseful and wishes he could right the wrongs. but it doesn't even matter. don't evaluate him, your marriage, or the situation based on what's in his heart - it is not productive, and it will make you crazy.
