Brooklyn Mom has given you some great advice. I'm sorry you are hear. I know you are in a difficult place and you should focus on you and your children.
One thing I differ on.....IC is only beneficial if a) someone is honest and b) thru are willing to do the work. Those 2 criteria alone are giant obstacles for most. Should your h seek IC? Probably. However, if he isn't honest or committed to addressing his issues, you may as well flush $$$$ down the toilet.
Take care of yourself and let your h deal with his stuff.
