AITA for refusing to meet my friend’s love interest?

I [24W] have a good friend (Victoria) which I’ve only known for one year but got close to really fast.

For some context, Victoria has gotten herself into a situation I have been vocal about not approving. She has another friend who she’s not particularly fond of due to how clingy she is (Jane). Jane doesn’t have a lot of friends and she’s pushy when it comes to hanging out which particularly annoys Victoria and to be honest I understand. On occasion she literally weaponises pity.

Victoria however seems to think it’s okay to mistreat her since in her mind they aren’t really that close. Jane told her about a common friend of theirs whom she had a crush on and asked Victoria to look for signs that he might like Jane. Their friend proceeded to hit on Victoria instead. She didn’t mention anything to Jane and in the beginning she was ignoring him but later on agreed to go out with him. Now they’ve been sneaking behind Jane’s back. Victoria even told him Jane had a crush on him supposedly so that he didn’t spill anything. I told Victoria that she needs to put an end to this especially considering she admitted to just liking the attention she got from him and she’s relocating soon.

She says she should/she will but it doesn’t seem like she’s planning on it. Lately she’s involving me in her lies as well. Jane invited her on a vacation but to avoid the pity tactics that Victoria uses, she lied to her about the reason why she wouldn’t go. Later and without me knowing, I also told Victoria to come to my summer house. She then begged me not to post anything in case Jane saw and to lie if she asks anything. I told her she needed to be upfront because I don’t feel comfortable lying.

I don’t know what she told her but I posted during our trip anyways. Now we’re going to a concert with my boyfriend and Victoria and she was wondering if she can bring the guy over for a bit since he’s going too. I so don’t want to meet that guy. I feel like she’s making me a part of this when I don’t even wanna be. Not telling Jane about this makes me feel uncomfortable enough. Let alone participating. I am also worried that Victoria might do the same thing to me, I don’t even know if I can trust her around my boyfriend. Finally the concert was a gift for me and since I love this band I will be getting quite emotional and I feel like having a random dude with will spoil the night for me and my boyfriend so.. AITA for refusing to meet him?
