Are all guys the same? I just want to find someone who doesnt want to look at every girl that walks by?

Or says insensitive things. And doesn't lie. I'm pretty and no I'm not one of those shallow conceded girks. But I do know that I'm attracted and I have a lot of guys who hit on me. I have dated losers and now I'm dating a kinda needy guy thinking he would appreciate me more than the jerks in the past and no I'm wrong. He comments on other girls in front of me, he doesn't act happy to see me, and he says the most insensitive things. He lied to me about smoking weed even tho I said I don't give a damn. Even flirted with this skank *** married girl at work in front of me. Why are most guys like this?
