This is oh so true! The best people come along out of the blue when you are not looking for them.. When you are comfortable in yourself and know where you are heading, you become so much more appealing to men.
I'm sorry to say that being needy is quite a turn off for guys, plus not everyone you meet wants to start a huge full blown relationship right from the get go, quite often this alone frightens men off.. Try developing friendships first and see where it goes from there, try not to read too much into things and over analyse and just take one day at a time.
Is there something you have always wanted to do, a hobby or something that would get you out and meeting people with simular interests? I think that maybe it's because you are lonely that you are putting so much emphasis in having to have a relationship.. Get the girls round, get TONS of ice cream and a chick flick and let your hair down a bit!
