Wow, that’s a lot of pressure on a girl… She not only has to be all the things you expect from her, but also love someone who does not really like himself and tries really hard to be some kind of “image”! This can only lead to a relationship where both try to keep up a facade all the time.
Seriously, a good relationship is not about looks! Studies show that attractive women tend to settle with less attractive men 😉

You should be loved for who you are, including your weaknesses!
I agree with popi that you need to built confidence. How is this done? Strangely it is done by accepting your weaknesses! Accept that you are not perfect, that others might look better, be funnier, have it easier to talk to people. You are completely ok, even if certain women reject you. Maybe they are the wrong ones for you?

You cannot change the boots you are walking in (your self, which you need to accept), but you can change the path you are walking on (a life and a relationship that is suited to your actual needs, not those of the person you try to be!)
