You are judging me when you do not know me. So you are being very rude

You consider it rude because you don't want to hear the truth. It's not like you've been seriously dating this girl for ages. How many threads did you open about the same subject? How can you think that this isn't obsession?

not to mention that women are very complicated. And, 28 is not my real age, I am older. And if you want to know why I never had a girlfriend, let alone, sex, there are reasons to it.

Women are just like men. And don't you think your attitude/behaviour etc. might play into this? People like other people who're confident, know what they want, don't play games etc. Just from this post I can tell you that you come off too strong, which is really off-putting.

Experiences shape us in many ways, and yes while I was friendly and very gentleman-like with this new girl, the moment I feel she may be taking me for granted, I do all I can to not allow her to do so more to keep my dignity in tact. She had seemed responsive up until then, why sudden change?

I think you'd profit a lot from some therapy to work on self-awareness and how other people react to you.

Cool, I did the IB, are you teaching that too?

I haven't until now, where I live, it's not really that popular.
