How do you guys deal, in the romantic sense, with attachments, knowing that it can't work out with someone? Like if you know they aren't into you, or if they have a significant other? For myself, I have found myself feeling attached to girls I am interested in, despite knowing that it is not mutual or that they clearly are with someone else, which sounds irrational but as someone with BPD I don't always feel I have control over my emotions. What are your thoughts on dealing with these kinds of things, or just resolving romantic attachment issues in general?
