Throwing In The Towel

I have to stop trying. It's truely pointless. I don't see the point is trying to impress a cute guy, when clearly they aren't interested. Even the ones that were interested aren't anymore. Is it me? Or them? I still don't know the answer. It's bothered me for sometime now. I finally just decided I'm not going even try anymore. I have to face the fact I'm going to be alone for a long while. Why is it, the guy you are attracted too doesn't even see you? Then there are the guys who won't leave you alone but you have no interest in them what so ever. It's a never ending circle. Someone will always want someone they can't have. I just give up.
