Emotional outburst

Me and my boyfriend have been year and a half we are in love, we talked about marriage and having kids. Recently I did some snooping and found out he had multiple side chicks I got angry so I did the unthinkable and slashed his tires and set his car on fire, this isn’t our first fight we have fought before and got back together, I feel bad for my actions and even tho I set his car on fire he still refused to call the police but he is mad at me I am in love with him and even tho I’m hurt I still want to be with him but I’m scared that this is it and he won’t come back my question to you all do you think he will come back or did I go to far?
