I have rejected people without knowing I was doing it. Sometimes it was years later I realised that a man had said or done something that indicated he was interested in me. In some cases I didn't realise what was going on and so just didn't do whatever I was supposed to do, in others I had some idea, but started to feel fearful and just had to escape.
All The Time said:
I practice the art of pre-emptive breakup.
Yes, I can just about identify with that. I practice a pre-emptive "go away and leave me alone" manner when interacting with men socially. No need to break up or reject someone outright when your expression and body language say "f*** off, I wish you were dead".
Honestly it really works! I'm 33 and have had only a couple of dates in my entire life, and I'm a virgin. (If there was an emoticon for "banging head against wall" I'd use it here.)
Of course I don't really want this. I'm working on it. And it WILL get better (I am nothing if not determined).
