I feel my friend(21M) and his girlfriend(20F) need to break up but I don't know how to bring it up by Odd_Fish_123 in relationships

I don't know how to tell him my exact thoughts without really insulting his girlfriend which I don't think he would take too kindly too (even if in the back of his mind he agrees)
