What it says on the tin. I need to complain lol.
But anyway, in High School two of my closest friends were twins. I'll call them Ana and Beth, because I don't like to use real names. So anyway, I was closer with Ana because I just had more classes with her. She was also the first one I met, I didn't really know Beth well until High School. (I met Ana in 7th grade.) In junior year Ana started dating this guy, who I'll call Dave, but it didn't really effect anything. And we all stayed friends through high school and for a good while after. I went over their house a lot during the summer and they came to mine a lot. The longer Ana was dating Dave the more friends she lost, because she spent more time around him than them. None of them ever liked Dave (and neither do I) which I think has a lot to do with it. By the time High School ended I was one of the last friends she had.
So anyway, we all go to our local community college but at different times. Beth and I go in the morning while Ana and Dave go in the evening. It had been a month since I had seen Ana because of work and school and just being busy. When Ana came to school in the morning, I forget why, she just gave me the cold shoulder. The last time we had seen each other everything was fine. I thought that maybe she was just having a bad day or something. But the moment her sister's class ended she was all perky and cheerful and clingy. Later when I asked her sister what I had done to get that reaction from her she (Beth) said I did nothing. That now Ana only hung out with Dave. And that if you don't think high and mighty of Dave, unless you're family, she won't talk to you.
And I wouldn't have problems being friends with Dave if he wasn't the most arrogant person I have ever met. Seriously, you score higher on a test or get a better grade in the same class it's because you cheated or sucked up to the teacher. It's pretty much the same for everything. He thinks he is better than everyone and everything. He always talks down and bad about everyone.
There really isn't any problem with us. I don't talk to her any more and she doesn't talk to me. The only irritating thing is now that she has no friends Beth invites her to places we already made plans for because she feels bad for her. And of course she has to bring Dave along. And it's not just me. Both Beth and her mom have said that since Ana started dating Dave she has turned into a bitch. (That is literally what her mother said. "I hate to say it about my daughter but ever since she started dating Dave she's turned in a bitch.")
And Ana also complains she has no friends to hang out with now. Who's fault is that, I wonder? Hell, even after she gave me the cold shoulder I have offered to make plans and hang out because I felt bad but she refused. That stopped like a month ago, though. (Trying to continue to be friends.)
Sorry about the walls of text. (Also I wasn't really sure where the put this. Since is sort of an issue I put it here.)
TL;DR - Old friend lost all her friends (including me) ever since she started dating her boyfriend. Now she wants to always hang out with her sister who is also my friend. Awkwardness ensues.

Meh, it sucks, but if anything, you're being a good friend to Beth by letting her sister and bf tag along on your plans?

I'm not going to stop Beth from letting her sister come along. They are really close. It just makes hanging out with Beth super awkward.

That's a tough situation. I've had that happen, being friends with families. You can't always be close with all of them unfortunately. What makes it harder is that you WERE close of course. But Ana is going to have to learn the hard way that unless she fixes her act then she's going to have no one but her precious asshole Dave. I'm guessing she's been confronted about this before? I mean, have you actually told her these issues? Saying "I have tried to be a good friend, make plans, and you kept blowing me off. Either get your head out of Dave's ass and have other friends too or stop complaining." Or do you think that would make things too awkward or tense with Beth? But if Beth agrees, I don't see a problem.
Also you could suggest to Beth to proclaim some events a GIRLS NIGHT OUT where Dave is not invited. If Ana doesn't like it she can miss out by her own choice. She might get lonely enough to try. And if she goes for it then she might remember how much fun it is without him.
I should totally have a girls night out 000:
I haven't really talked to her about because each time I have tried to say, well, anything, she ignores me. But this is something I know her parents and sister have already said to her. I don't think my input will change her mind.
But shoot, maybe spending time away from Dave will make her friendlier again. I hope so, she used to be really nice.
