Being forced to go places by my dad

I’m 19 years old and my dad is making me go with him to some church festival and I most def don’t want to spend my Friday night that way. Don’t get me wrong, I’m religious and actually enjoy going to church every week, but this festival is in the way of my plans. I’m also annoyed because I’m 19 and I’m STILL being forced to go to places I don’t have to be. Deadass I’m the only ‘kid’ around because my dads friends don’t force their kids to go because “they’re old enough”. I’m 19 not 9. Another reason why i don’t wanna go is because my dad and I have a bad relationship, he’s cheated on my mom several times and has a gambling problem and I don’t wanna be near him as much anymore.
