My girfriend's dad hates my guts
So let me lay it down. I'm a 6'5" kid with a brite purple mohoawk. i'm very independent and "free spirited". i don't do drugs or drink, in fact i'm a pretty good kid. in fact, if it wasn't for my mohawk, people wouldn't notice me. i'm a boy scout, have been for many years, on my way to eagle. i have a steady job, a car. i know where i want to go in life. however, i started datin my girlfriend about 3 months ago. since that time it's become apparent that her father hates my guts, well actually how he described it to my girlfriend is he "doesn't approve of me". he's also a tall guy, similar build as me. he is also very religiuos and very consevitive. you can see why he might not "approve" of me. I've tried many times to open up to him and get to know him better, I've invited him to my house for dinner multiple times, yet he refuses to get to know me. What should I do to gain his trust and approval?
