Should I have gone in this awkward situation?

I am 25, married, and living on my own with my husband.

My parents have been having horrible problems in their relationship. It has been so awkward during the holidays see my dad treat her badly and my mom shut down. My mom isn't perfect, but I have felt a lot of anger towards my dad for acting like a 3 year old not getting his way.

Long story short, my mom and dad are heading back here where I live after a road trip. I've already seen both of them already during Christmas. The initial plan was for my mom to drop my dad off at the airport and she and I would have lunch and spend today and tomorrow together. She texts me at 9:00 this morning and says they are making good time, would I want to go with them to take my dad to the airport?

I initially used the excuse that my husband was sick and came home from work and that I wanted to be with him until he woke up in case he needed me. That was part of the reason, but most of the reason was that I didn't want another awkward 2 hours with my parents together. I was pissed at my dad for throwing a hissy fit at a restaurant the day after Christmas, throwing a tray down and giving my mom a horrible look when she was just trying to help.

I don't want to see him right now, and I especially don't want to see them together because they don't love each other. I'm hoping they get a divorce, but until then, or until something works out, I'm not sure how I should react when they say they want to see me.

Should I have sucked it up and gone? Part of me says yes because my dad still loves me. But most of me says no because he's a two-faced asshole and I don't want to be around him.
