I don't like my boyfriends friends! Need a new strategy. Help. 10 pts.?

Ok.. So since I met them, I have not liked them. They are extremely immature, sometimes its unbearable. Despite this, I've tried to get along with them for my boyfriends sake. I've even made brownies and cheesecakes for these idiots. I've tried to be very very nice. But all I feel from most of their part is pure Rejection. They don't like me (Im sure), and I don't like them either. I make my boyfriend extremely happy and they know this, but they have also witnesses various arguments between us... and cause they don't like me.. they make my boyfriend doubt our relationship. I don't know what strategy to use with these morons anymore. I want to conserve my relationship. Thank you.
