Toxic relationship also- I finally got away from her, and about a month after going away with the true decision to not allow her any further contact to me, thus preventing the harm of her attacking and manipulation behavior - I encountered what aromantic is, while looking into panromantic as someone I had met identifies.
Finding this has given me a frame to understand why I never felt comfortable in the parts of interaction that are strictly romantic attraction based. I feel that this trait tracks with my nonverbal nature and the way I am that came to be described as a natural hermit. The reason these mishaps took place the way they did is that i am heterosexual and have a lot of physical needs, and all of my partners have been mismatched, resulting in conflict and tension around romance.
