I want to skip my brother in laws wedding
How does your brother in law feel about this?
I don't care what he thinks, I'm going to miss the fucking wedding and he can't do anything about it.
You should not miss a family member's important event even if you are not very fond of him. You should do your best to support your family the best you can if you are able to.
I'm not going to some fucking wedding just to support him, it is not something that I feel like doing.
Is there a reason why you do not want to go? In order for me to support this, I would need a reason more than simply not wanting to go.
