How would you say I Iook?

What is considered attractive? I mean what do you think? I'm not fishing for compliments, because i've honestly never considered myself attractive. I just need some help to "get back in the game" so to speak. I haven't dated in awhile, so what are some suggestions to help me out with my appearance? The last girl I dated was over a year and a half ago. Things were great for about eight months then she decided to be a giant slut and give three guys a lap dance. She then defended herself by saying "it's just dancing". What do you think? I thought it was whoreish, so I ended things. Who was in the wrong?

And please give me some pointers on how to meet people, and what to say. I know this is more then what this question was supposed to be, so whatever you contribute will be greaty appreciated. Thanks. - Matt
