If you don't spend time with your partner's friends or engage in their social life, you may believe the relationship won't endure. Yes and no, in that order. Yes, meeting your partner's friends and hanging out with them on occasion is completely acceptable if all of you want to. However, it is totally common not to do so. The important thing is that you are happy with the way things are between you. If you aren't, talk about it with him/her. Maybe the guys like you to be more involved in their lives and the girls might want you to pay attention to them too. Whatever the case may be, work together on creating a shared culture that is comfortable for everyone. In conclusion, yes, it is okay if you don't want to hang out with your boyfriend's friends because they're stupid or whatever but you should still stay together. If you break up, you'll probably never talk to each other again which is a waste of time and energy. Save your fights for when it counts most - in front of the people who matter.
