Everyday I get deeper in confusion

I don't know what I want. My problem is I crush really hard. It seems that every guy I like doesn't want a relationship, or doesn't want to date me. I like the fun flirtatiousness and everything that leads to, but I know that this will only set me up for heartache. I keep giving my whole self in these situations. I don't know why I cling to it. Is it because I like being told I'm beautiful? I know I'm attractive. What is it about hearing it from someone else? I keep changing my mind. Saying I want these things and then I say that I don't. These guys... some of them are amazing and so understanding. Frustrates me even more that they don't want to date me. Some guys are nice guys, but will try tempting me. Frustrates me that they don't respect me but it's attention. I like not feeling invisible. I really don't know what I want. I want to have fun, I feel like at the end of the day I will just be alone. I just don't get it. I'm told I'm pretty and funny and that any guy would be lucky to have me. None of these guys want to be that lucky guy. Are they lying to me? Am I repulsive? I am happy being single. I just would feel better about the choices I was making if I knew these people actually cared about me.

to top it off i have this battle going on. I know I shouldn't be making these choices. I keep doing so. Then i try not to but then I fall again. Wish I knew what I wanted
