It happened to me recently at work. I don't even find her physically attractive, and her personality is not what I'm into at all. But I was still somehow attracted to her - and she also was to me. She didn't like me, and I certainly am not the kind of man she goes for. It's like we had a strong connection in one area beneath the subconscious or something, but every other area was completely incompatible. Aggressively so.
Anyone else have anything similar?
Yes. Many times. I'm a woman btw. I never got anywhere with these people though, probably for the best. (Not sure if in your case you did?)
As in, hook up with the person? Haha no that didn't happen. I thought the same as you, probably for the best.
