Guys, Do you get angry if your girlfriend cheats back?

Ok so I have been in a long term relationship with a guy that cheated on me in the beginning of our relationship. I forgave him but I was extremely hurt so I cheated back and never told him about it. My question is if he finds out do you think he will he hurt or upset? FYI it was with someone he knew.
