Gather 'round, children, I got a question to pose.
Now. You're in a relationship, right? Everything's splendid. You have your friends, your s.o. has their friends. There's one, maybe two, friends in particular you're not too fond of, but you don't pay them any mind, because you can't control who your s.o. hangs out with. You learn to deal. But for what ever reason, one of these friends just really gets to you. Something about this person seriously rubs you the wrong way. Now, whenever they hang out, you can't get in contact with your s.o. for multiple hours, sometimes not until the next day. This becomes annoying as shit. Note, it only happens when (s)he is out with this one friend in particular. You ignore it, assuming maybe you're thinking too far into it, (s)he's just busy this one time. But it keeps happening. When this one friend is around. Then it turns into a problem when you actually have a fight about how they have a tendency to neglect you when they go out. You don't even mention the friend yet. But you get upset because, not only have they not contacted you that entire day, and their reason for not doing so was being out with a few friends, but (s)he has the nerve to get upset because you said something. "You can ditch me for your friends for 12 hours and I'm just supposed to be ok?" you argue. "Well, I'm not..." And without getting belligerent and unruly and flat out angry, you point this out, and they get angry with you....wait, what? So then, you make up and everything's cool after you talk it out. But then (s)he does it again. -___- So, jokingly, you finally mention this friend, and say that (s)he can't hang out with that friend anymore. JOKINGLY, mind you. (S)he laughs, and says "that's not true." Oh, but it is, my friend. It is. It happens yet again after this, and you say the same thing. (S)he admits that, yeah, that happens. "I'm sorry, I'm really trying." That's great and all, but (s)he's not making much progress. Sure, instead of 12 hours, (s)he went missing for 6. But still. It was with that friend that (s)he disappeared. So it kinda sucks. Part of you starts to get serious about severing ties with this cow/douche, but you can't do that. That's against the rules. Then, on top of all of this, they get home after they decide they'll "talk to you later" and they're too tired to do so. Every time...
I guess my question to the world is this: What do you do in this situation?
Do you start to get serious about the "stop hanging out with him/her" thing? I mean (s)he admitted that it does happen regularly. That's just proving your point. Additionally, you know (s)he would throw a little fit if you even so much as mentioned hanging out with your bff without them around, seeing as (s)he once mentioned before that (s)he was, low key, jealous of your best friend. (S)he even said that (s)he was starting to dislike their "friend" anyway. So what do you do here?
