Very often this is due to a too high strip. Near simply is not the person who would fit all their requirements. They set a certain level below which the "ideal" man shall not fall. It is natural that girls like clever, kind, beautiful and talented men, but there is not even the point. Many beautiful and successful girls do not like some little things that others do not pay attention to.
The second reason could be your perfection. Men are just afraid in your presence blurt out something stupid. They feel that they are not quite comfortable in the society of a woman like you. Of course, do not pretend to be stupid too specifically. But be smart and not worth it. After all, think for yourself which of the men want to kiss the encyclopedia?
Another reason often becomes too serious in a relationship, as well as your plans for the future. Men appreciate freedom. Therefore aloud at the first date do not need to plan how you are thinking of the weekend to go to the countryside or going on a vacation to rest.
Reason number four - your behavior in the initial stages of dating. Beautiful and successful ladies often seek to present himself as a man in such a light that seemed to them by their elected representatives as of the opposite sex do not have to.
Just cause loneliness may serve as excessive arrogance. No need to look at the men down with contempt. They will appreciate the girl more sublime than themselves not as you would like. You show them completely inaccessible.
And this is just the basic, most common causes of loneliness. If you have decided on what you have a problem, try to fight it. And it should be done not by expensive creams, cosmetics and clothes, and psychologically, identifying ways to resolve the problem.
