Now I know a lot of people that have had similar feelings, myself included for a time. I learned something very quickly though that helped me out.
"If you want things to change you need to start by changing yourself!"
People that constantly blame people of the opposite sex for not wanting to pay attention to them may have to make a change to get people of the opposite sex attracted to them.
A 25+ year old guy living in his parents basement, working as a pizza delivery man, about 100 lbs over weight, that spends all day playing X-box or Role play games with his buds, and driving a 1989 Toyota Tercel needs to start thinking about changing himself to become someone women will be interested in!
If you are constantly attracting the wrong people of the opposite sex, maybe you need to change where you hang out or how you come across. If a girl comes across frumpy and boring guys don't want to hang around with them cause it is like being neutered. If she comes across as easy, only the guys that are looking at tonight are going to be interested.
Might be a little blunt, but it is true!
