Some women are so damaged from their past R's (or egotistical) that they think any guy that so much as nods at them is hitting on them or interested in them.
For instance, I went to the grocery store today. I was trying to reach something on the upper shelf and was standing on the lower one trying to get it. A nice man came over and said "would you like a boost or can I just get that for you?" "Some" women would feel insulted by his offer of help or think he was trying to hit on her. I felt neither. I just wanted the damned box and "finally" was going to get it without killing myself.
There are good men out there but if you're not attracting them, the first thing you need to question is what vibe are you putting out that's attracting the jerks.
