I agree with you about "signals" we may be sending out. It must be subconscious because most of the time I feel confident around others and I'm sure my body language says the same thing, I am even bold and bitchy too sometimes. But those "signals" obviously are still being picked up on saying "I'm not good enough for a quality, nice people" and "come to me weirdos, nuts, and psychos, cuz I don't deserve any better". Oh, and stalkers, I'm allll yours, YIKES!
I'll email you and see if we can figure out how to remedy this problem, I think I know why this is happening, and I'm working on it.
