Cleanse my relationship

My bf and I love each other a lot. When we are good we make the best memories but when we are fighting even cops get called. Idk what to do. He is so kind and loving but I don’t want to be with him if we are going to keep fighting like this. I’m 21 and ready to have my own family. What are some things I can do so we don’t fight no more. It really breaks my heart
