Cheating rant!🔫🔫

I have been with my so for almost a year and for a good two months he had been cheating on me with the same girl...only when he was shitfaced...but we fixed things and moved on. For the past couple of nights when I drive home from work I have been seeing him talking to this girl outside a bar. I drive the same route home from work at the same time so I'm definitely not trying to spy on him he knows this. It's so fucking frustrating when I told him not to talk to her or be friends with her. Am I wrong for getting upset because I'm about ready to leave his ass. I'm fucking done being hurt all the time and getting pissed.
