Confused

Hello, I've been married 13 years. Been good and bad but we always had each other back. I just found out he cheated twice with 2 different women. One he works with them they no he's married and who I am. Really want to beat their asses but I'm not. I'm totally devastated by him he's my best friend. Then I'm sick every time I look at him. The plain disrespect and the lies. I no I need to leave him cause I can't accept this. But I don't no that I can again I love this man with all of me .
