Well I was having this conversation with my sister the other week and I was saying to her that sometimes when you meet a girl and she shows that she's really interested in you without holding it back then that becomes the way you understand a girl shows you that she likes you. I mean she's bridged the gap and that creates a certain sense of certainty but unfortunately the difficulty is no two women are exactly the same. So what develops is a certain preference for how a girl shows she likes you or that she's interested.
example: she asks a friend for your phone number. When that girl did that there was no way I could miss the sign. She was doing that for me. However that also raises the bar or expectations. She put herself on the line. I have a harder time seeing that a girl likes me who is not as bold or daring.
example: she pushes away guys who try to hit on her. So basically trust level is through the roof. I can trust this girl without having to second guess myself. There's definitely a sense of maturity and respect. Of course I do the same for her as she does for me.
example: no drama when it comes to sex. Admittedly, I was with an older women who had plenty of experience so she understood why she was there and what we were going to do. Not only did I enjoy it but I was really impressed with how comfortable she made me feel.
Here's some common bad examples:
example: She dates other guys to make you jealous. Seeing other people is fine but it's embarrasing when she's using other guys to make someone jealous. Slightly pathetic. That of course creates doubt and mistrust. Even when she stops this behaviour that lingering feeling of doubt remains. Plus it usually ends in failure. What I mean to say jeasouly usually makes the woman less attractive. She is a source of pain instead of happiness.
example: She has other people speak for her because she does not have the nerve herself. I can understand that but I do not find that attractive using a middle man to get your point of view across. She will not talk to you but instead her friend will and though we can not exactly say it we're talking about her. It comes across as manipulative on her part.
example: She's out of touch with her sexual nature. Physically there is no difference but pyschologically, the experience is ruined. Intially she will act morally righteous but then when you finally do the deed she enjoys it as much as you do. However because you had to beg or plead to sleep together, there remains a bitter feeling. Basically she's not open to experience.
I wish I had more examples but I'm coming up short. My point is that when you've had better that becomes the standard. What I mean to say is certain women impress me with their behaviour and others depress me. Maybe I have a thing for strong women.
