I would agree w/you there, FF.
I used to be that way.
But then I got tired of feeling rejected for nothing.
And still felt the need ofr a good screw every now and again, however.
So the less I knew them, the better. And I made sure to get rid of them or get out before I learned too much about them.
B/c I didn't trust myself to be able to divorce my feelings from what I was doing.
So I'd move on asap.
