How do I deal with my boyfriend's friends. I don't like them and they're disrespectful?

If your boyfriend chooses his friends over you, then it's probably time to dump him. If he really cares for you, he'll realise he's made a mistake and make a compromise. His friends sound like idiots and him not choosing you over them makes him seem like an idiot. Definitely dump him, he'll probably realise he's made a mistake and come back to you.
