Ex messaged me saying “don’t talk to my friends again bitch. I know you messaged (his friends name)” He’s never called me names. I said “I messaged him ONE TIME. it was A WHILE AGO” ex blocks me and later apologized an hour later saying “I’m sorry for saying that. But I’m serious though please don’t message my friends”. We exchange a few words a few days later. He says “don’t message my friends *thats crossing the line*” what does he mean by that’s crossing the line?
