How I feel...

So, I know this is totally off topic of Fantage, but i'm in a really bad mood today.
Recently, I found out my best friend was dating my ex-boyfriend.
Let me re-phrase that...
My best friend is dating my ex-boyfriend
Oh yes, it's true.
I was so mad and tried acting cool but deep down I was like...

So do I have the right to be upset, angry, insecure, and betrayed?
I really liked the kid. It's not like it was a 2 week relationship, it was a few months. My ex friend and I had already gotten into multiple fights. It sucks cause she can use that against me....
This is really getting to me.
I've came to the conclusion....
