AITA for using a card game to get out of being around my father in law?

I've been dating my gf for 5 years and engaged for 2. I am close with everyone in her family, save for her dad who I really don't like. This has made my gf really sad because she thought me and her dad would be the best of friends because we have a lot of things in common.

I don't want to go over the reasons why we don't like each other but the last time we interacted was because he came over to my house and he told a joke that I didn't the joke was funny. Him, my gf's mom and my gf tried to get me to laugh by explaining the joke to me. I said "I got the joke, it's just not funny" he then insulted me and called me a cad and I just told him "uh huh" and left it alone.

We have Thanksgiving coming up soon and my gf invited her dad to have it with us. He said he couldn't come because he had to go spend it with his other family. Apparently they had a work around where they would come and spend it on a day where I was already planning on spending time with my friends. My gf told me I would need to cancel the date so we could spend time with her dad.

Now my gf and I are playing this couples card game where basically you give your partner a card and they need to fulfil the conditions of that card. She used a card on me a few weeks ago so I used a card on her which was called "My condolences" basically it's a card that allows you to back out of any planned event you don't want to go to. When I played that on my gf she got really upset. She told me she couldn't believe I would use that card out of spending time with her dad. I told her she could go spend time with him, but I didn't want to cancel on my friends to hangout with a dude I don't like. She told me that she is reconsidering the whole marriage because of this.
