Dad refuses to meet my baby daddy's family?

I dont really know what answer im looking for, I guess advice? Im pregnant with my first child and my dad is refusing to meet my boyfriend's family. My boyfriend did call him when he was mad at me during a argument we had and according to my dad they exchanged words. I dont know if what type, its not okay but my dad just said "he was a total jerk".
My dad is one of the biggest jerks alive so it almost takes one to know one lol. Its annoying for me because his stepmom and father are doing everything to help with the baby while my dad isn't doing anything.. they are buying everything we need for the baby and she's trying to have a combined baby shower, which is what I want too but now he wants to have his own baby shower and wants nothing to do with any of them... what do i do?
