I rarely respond to posts, but relate so much to yours. Sorry to hear its going so badly for you. I've never had much luck with dating sites either, but have tried them several times over the past few years. Free or pay sites are all the same. They prey on people who are lonely and somewhat introverted like myself. It really sucks because it could be such a good thing. People are very often dishonest about themselves, their intentions, age, size, marital status... fill in the blank. Its almost like everyone is looking for the next better guy and the truth is no one wants to be runner up. No one deserves to be ru ner up. Often very high hopes were followed by couninuous disappointment. I would get discouraged and get off for a while vowing that I was done with it only to get bored or lonely and give it another try. I met several people over the years and am glad to say they became good friends, but I wasn't looking for friends. So what good did it do me?
I suppose the point to all this is just to say, you're not the only one. If you think it seems desperate, then it probably is. I wouldn't push them as it will only let you down even further. The truth is, if its the right person, you will never have to wonder about it. Things will fall into place. So hold your head up and don't give up. The way I began to look at it was every disappointment and day I hung in there brought me one day closer to finding the right one. Your time is coming.

Good luck
