Do you believe in “getting even?” (Read caption)

Sometimes i unintentionally upset my boyfriend or make him feel bad or unappreciated about something. He then will need space, and when we start talking again he says “you made me feel bad, so now you now how it feels to feel unappreciated”. He does this and he believes in getting even. But i believe you cant fight fire with fire and that two wrongs don’t make a right. What do you ladies think? We do communicate really well. But he seems to let his ego get in the way or be a little stubborn when it comes to this.
