Did I do the right thing?

okay.. so this guy my girlfriend was texting my girlfriend.. he said he was upset about girl problems. he said to her he wishes she was his gf, she said why and he said shes straightforward fit, and a lovely girl. she told me about this and at first i wanted to knock his teeth down his f****** throat. then i calmed down and said not to be doing stuff like that again. i said i wouldnt hit him over it as it wasnt worth it. i said he wouldnt appreciate it if the same thing was happening to him.. then he apologized and said he would stop talking to her altogether. i said i dont mind him talking to her as long as he didnt do that kind of stuff again.
