I don't want to ask my dad for money

Hello all Lately my mother has been pressuring me to ask my father for money for the wedding. I never really planned on asking either parent for money. I was just going to save with FH once school ends and have a small wedding at his parents house or a local bed and breakfast. My mom gets very angry when I tell her I won't ask though because she feels her children are letting him off easy again. When my two sisters and I were just kids my parents divorced because my dad was abusive to my mom. My mom could've had him thrown in jail but her lawyer advised to keep him around because we desperately needed the child support (my mom was a stay at home mom till then). So my mom did and worked hard to support us and pay the rest of our funds. My dad was legally bound to pay half of his kids expenses for things like school until we graduated, though he seemed to do it begrudgingly. We visited him during the summer and certain weekends. continued in comments
