But there's one in particular I'm really fucked up over because she was introduced to him while she was dating one of his other friends, cheated on that friend, was sworn off by him, and then they became friends again after he broke up with me last summer, and fucked each other all summer. We're back together, and I'm uncomfortable with him being friends with this person. I actually want to hurt her and everything she cares about so I need to address that in therapy. But am I bugging for not wanting him to be friends with her, or is this a justified response?
