This thing keeps happening to me where I make a new online friend, but then it somehow turns into a flirty relationship. Problem is I'm already taken and I do always tell them but they still end up wanting to be with me anyway, and I don't know how to deal with it so we just drift apart eventually. This is maybe the 4th time its happened, and we were getting along so well, but now he's declared his feelings and wants to be with me and now its all messed up cause of me.
