All sex no love?!

I have just recently started dating after such a very long time.  I feel ready and able and even willing to put forth the effort to a possible relationship.  Why is it though, that I  keep attracting the wrong guys? I don't think I'm ugly, but I also certainly don't think i am the most beautiful. They come, they say all the right things, I believe, I settle in and get comfortable after a while of getting to know him, one thing leads to another, we share a night of passion and soon after, he's gone!

I could very easily turn my thoughts and plans around and do as they do, what is that saying? When in Rome...but I sure would like to hear from the guys in here....what is the thought process? Do you really say all those pretty words just to end up between the sheets? Honest answers will be extremely appreciated! No judging on my part.
