I asked him what his intentions are, and he said he's not planning on moving in with her, but he said so many things.. Only half of it is true. What if next week he thinks something different? I'm really confused.. Really really confused as to what I should do..
AH,
Why are you leaving the decisions to HIM, the one person right now who DOESN'T have your marriage's best interests at heart?
If you don't have a plan (and I agree, it can be VERY scary), then I suggest that's where you focus your efforts right now. Emotionally detaching yourself from your husband -- and his poor, destructive behavior -- while you focus on a financial, legal and emotional plan for yourself. There are women's groups and legal aid societies that you can talk to, who can help. This will EMPOWER you, and I think that's what you need right now.
Your husband is NOT the only one here affected to gets to make all of the decisions.
