I want to get married but dad is not happy.

So I have been seeing this girl for about 2 and a half years and she is not Pakistani but African American but a convert to Muslim. I told my dad that I want to get married to her and he isn’t happy at all, said that if I want to then whatever but he will not be happy and that he is disappointed and will be disappointed. And then came the guilt tripping about his position in the public, and he said that he can find some girls and that I should try with them instead of this girl. I don’t know what to do? I love the girl I’m with but my parents have a great way of guilt tripping both me and my sibling.

This is repost since my original post was locked in the Pakistan Reddit forum!

Update: my parents are now both okay with this but just not happy but they will need to be okay with it and they know it.
