>>15210I was pining for this girl who seemingly wasn't all that interested in relationships, but I was really adamant about getting with her. We were good friends before I confessed my feelings, and while she didn't reciprocate them she left the question open ended. This resulted in me getting really unhealthily attached to her and I became very emotionally abusive. We'd get into these big fights and break off then get back together every couple of months. It went on like this for many years.
After the longest of these break offs, when getting back in touch it was revealed that she'd gotten in a relationship with one of her other friends whom I'd known (and bitterly disliked because it was already known she was also into her). This really threw the future of our friendship in danger, I was acting especially dickish and constantly looking for ways to pick at their relationship. Eventually for reasons I've forgotten I ended up having a chat with her girlfriend. The way she spoke of me, it was really clear how much my friend valued my presence, and I realized how much of an ass I was acting.
In the end I was able to get my act together. Became a much better friend and both her and her girlfriend see me as someone they can come to for help or advice when things are bad.
I've since gone out of my way to learn a lot more about the nature of love and attraction, and do my best to not be ungrateful for the platonic love of those close to me.
