If it is me. I won't talk to the father in- law. In the future, anything, either tell you mother in-law or have your hu*****and talk to your father in-law. Keep doing whatever you did in the past with your mother in law. Birthday phone call, new year phone call etc. or just keep in touch with her as before. Now, depend on how your hu*****and handle his relationship with his father in the past. He can continue the same. After all that is his father. You can show you anger, but can't really expect him to not talk to him etc. but make sure your hu*****and handstand why you don't talk to your father in law and what happened etc. then see what happens, then change interaction if things get better.
