I'm giving up men - are there no good ones left?

I'm 33, attractive and intelligent with a great personality. I've spent my life looking for a truly good guy but all I seem to have met is players disguised as nice guys. They 've always been hurt by a woman in their recent past, and are looking for a nice honest girl which I am. The second they spend more than 5 minutes with me tho they are trying to get into my knickers. Its not like they disappear once we've done it - they always want more, but I feel thats all they want me for. I want a man who loves me for me. The ones who stick around long term start talking about our future together very early on and mention getting married (they start this not me) but after a couple of years they're still talking and keep saying "soon". In the meantime they have run my confidence into the ground. Eventually I leave. But I end up with the same type again, even though I always know guys as friends for ages first. Even online dating is the same.
