But why?

I'm sure being asked out by someone should flatter me.
I'm meant to feel good about myself now.
'Someone likes me :)'

But I don't.
I feel horrid, like I was just being a spoilt, picky, selfish bitch saying no.
Why do I feel like this though!? It's not my fault I just don't fancy him.

Maybe I should be less picky and take whatever I can get.
It's not as if I'll ever get much.
