my "Because my dad is keeping my life hostage."
This is Maya being a drama queen.
my "He fooled me into co-signing my student loan and afterward he gave me the ultimatum that I couldn't see Josy ever again."
This is the catalyst to Patrick needing to control every move she makes.
Who she stays with, who she sees and what she eats, what she wears. etc.
Patrick is a fucked-in-the-head religious bible-thumping extremist, that sees his daughter being a lesbian as a public humiliation. Hence so he will attempt to control every step she takes from that moment of embarrassment. It's not exclusively linked to Josy only. This is him feeling the need to untarnish his religious reputation in the eyes of his fake invented lord! because he is unable to accept his daughter for who she is.
So if you believe that having a "boy" chasing after her skirt will make him more malleable, you're sorely mistaken. He will probably cut your sausage off the moment he catches the MC checking out her legs...
PS: sorry if I offended some local bible-thumpers
(not sorry)
