After I fell out with my ex-best friend I started liking a boy she really hated.
Is it just because of the fallout?
No, I am just sick of her anyways so I thought it was time to give him a chance.
She sounds like she is a little spiteful too. However, you should not date someone just because your best friend does not like them. It looks like you're trying get back at her and it's wrong.
That's where I'm at!
It sounds like you got yourself in a pickle. Do you actually have feeling for him or are you just using him? Can you elaborate for me?
