girl that really is a horrible situation.. but heres the thing! THEY ARE STILL FAMILY!
You dont have to get along with them or like them but maybe once in a while you should take the time to allow them in your baby's life.. BUT make it STRICTLY just the grandparents and your baby! if anything! if your husband thinks that they shouldnt see that baby then that benefits everyone..
im in a tough spot too! My hubby's fam is kinda well ill use the term trailer trash. They smoke on top of everyone even if you ask them not too, that his aunts and grandma but his mom is an alchoholic who doesnt take care of herself and lives with a child malester! so i feel ya on the comfort level!
i have come to an agreement with don that once in a while would be suitable and to do it on terms that everyone agrees with. us at a hotel and absolutely no smoking and they could go to the park or hotel to see him etc....
so maybe you and your hubby and his parents can come to some type of agreement that way they arent involved in your life. they are involved in your baby's life.. talk to you hubby! see if he has any wants or suggestion!
hope any of this helps.. but please do whats in your heart and chat with your husband that is the best you can do! i wish you luck and hope things get better. maybe they will loosen up
