This is a tough situation.

If I were you, I wouldn't allow myself to be used as a tug of war or pawn by your parents or husband. Love them both, but have them in entirely separate buckets at the moment.

If your parents question/pester you, have answers ready such as:
"I can't speak for him"
"He is allowed to make his own decisions"
"We don't talk about you, so I don't know"
"While I love you guys, my husband is my first priority"
"Let's enjoy our time together, and leave him out of it"
"He's asked me not to discuss him with you, and I have to honor that".

These of course are generalizations, but the gist is to not let them use you for their ends.
Perhaps in time a heartfelt Sorry card might help mend the rift. I wish you the best in this situation.
