Family counseling is something I would expect to involve the members of an immediate family, like parents and children. I guess it can involve others, but thus sounds weird to me. The epilepsy is your husband's issue and it should be up to him if he wants counseling and who he wants to partake in that. I don't understand his parents initiating counseling. If I were you, I wouldn't be too interested in going. Sounds like the parents might want to ambush you.

If these people have been miserable to you, then you have every right to avoid them. I'ld be very suspicious of what they are intending. The whole thing sounds very inappropriate to me. Does your husvand really want to do this counseling thing with his parents? If so, he may be littke too much under the thumb of his folks.
