I (20 F) have started to develop feelings for my friend (22F), who is bi as well but unfortunately also the ex-girlfriend of my childhood guy friend (21M). I don’t know how this happened and I don’t want to like her like that, but I’ve started seeing her differently in the past couple months. I know she won’t feel the same way because 1) she still has feelings for him and they may get back together eventually and 2) I’m pretty sure sees me as a younger sister figure because of how we met. I feel like a terrible friend to both of them and I don’t know how to get over this while staying close with both of them—I really care about maintaining my friendships since we’re all in the same group. Please help :(
