lynn, if you are not yet divorced, can your husband legally take a second wife???

I do agree with the person who suggested you just dodge whatever he sends your way. It is good you are consulting legal help. After you have done so, I hope you feel free to let that man know that he will need to refer all questions and concerns to your lawyer.
IMHO - That really needs to become your standard response to him.

And, if it is any comfort to you - your children know already who is the good parent and who is not. As time goes on, you will see this.

((((lynn))) Hang tough - there are many of us who have walked in similar shoes and are here to support you.
