answer:My take, she probably doesn’t have a huge social group at the moment. She just got out of a long relationship, and typically in long relationships your friendships will suffer at least a bit, especially if you’re younger and not familiar with maintaining them. You introduced her to a group that you yourself said were fun, and she liked it.. so now she is trying to cement it and make friends with them. She may not be going about it in the best manner simply because she doesn’t have the social skills to organize large friend things like that. On top of that she’s trying to get you and your b/f to tag along because you are the most comfortable part of it for her, she knows you. It honestly sounds like you’re being a bit inconsiderate. But at the same time so is she. Honestly I wouldn’t worry about it. Either A) She’ll be accepted into the group and won’t have to use you and your bf as a link.. or B) She won’t be accepted into it and she’ll move on. Be a good cousin and help her out til one of those comes to fruition.
