Yes you are right sofacat. I know what I need to do and that is not let his parents come here. Maybe in the future when my AH gets more clean time under his belt. I guess this situation would be hard to handle even if my husband wasn't an addict.
I am ultimately hoping that with time my AH will come to realize exactly who his parents are and then be able to intelligently make a decision as to visitation arrangements. I don't know how this is all going to take place, but I'm sure it's going to be a bumpy ride.
