In love with my best friend and dating someone else...

I know I'm horrible.

I was in a bad place last year and met this guy and he helped me so much we became close and friends. We also slept together. I started to develop feelings for him and he stated he was not interested at all but still loved and cared about me as a friend. I respected that and tried moving on.

Now I've been dating this guy for about two months and I'm very happy it's not quite love for me but I believe one day it will be.... I was getting past my feelings for my friend until today.

He told me he brought a girl home. It felt like I was stabbed in the chest and I can feel myself crumbling. I shouldn't care, I should be happy for him, I have a boyfriend who is amazing and kind and loving and cherishes me....

but why does it hurt so much.
