How can I get my girlfriend's parents to like me?

[Teken]

So far it's been a month and a half into the relationship and I feel like my gf's parents are barring me from seeing her. We are high school age so ofc we still live with our parents but I feel like they bar me from seeing her anytime I try. There hasn't been much opportunity to make an impression because they wouldn't even open their house to me to do so. How do I deal with this? Should I just ride the wave and see if they come around? I get the notion that her parents don't like the fact that she has a bf but don't even outright stop her from having one. Instead they just prevent any means of me seeing her outside of classes.
