Does anyone's SO not like your parents/family?

I love my in-laws but SO can hardly tolerate my family (parents and sister). My parents constantly bicker and after nearly 30 years, I'm use to it and can basically tune things out, despite how much they annoy me. I spoke up once and threatened to go home before the weekend was over and my dad didnt talk to me for almost a week because he didn't like being "threatened" in his own home. We live 4 hours away and I said didn't want to spend my limited time off having to deal with their bickering because if creates a stressful environment. DH has "threatened" to speak up and say something next time since we shouldn't have to walk on eggshells because of them. I feel like DH is making me pick sides (sorta) while he feels like I'm not supporting him and thinking of his feelings. I don't know what the solution is or if there even is one...
