Sorry to hear you're having a hared time. When you say your husband is annoyed, do you mean with his parents or with you? Now that you're married, his main responsibility should be to you (except for in really unreasonable circumstances, obviously, which this doesn't sound like). Yes, they are and always will be his parents but he should be more supportive of you now. If he is also annoyed with them, can he not just have a quiet word with them and ask them to back off/pack it in etc? They should be told that they can't try and come between you two, done in a nice way so that they don't get offended and cause more problems... Good luck!
