How to deal with my in-laws and my husband.?

Kill them with kindness. Be extra special nice to them, hug them, tell them you love them. Ask if they need help with anything. Go overboard. The Kill them With Kindness really works. They won't know what to think. If they don't change any after a couple of months of this, then just talk to your husband that you can't take his parents behavior any longer, and start naming names. You have nothing to lose at this point. If your husband doesn't stand up for you, you don't deserve him. Then maybe it's just time to call it quits and divorce and move on.
