Advice

Two days ago my boyfriend and I got into an argument. We usually throw playful insults to each other (nothing too crazy), and I feel like he crossed the line by calling me a bitch and repeating it when I asked him what he had said. So fast forward to now, we haven't spoken at all and that's not like him to not talk to me. He told my guy best friend that he's not talking to me unless I approach him first and he thinks I was being overly sensitive. I would be truly heart broken to see out relationship end right before our 1 year anniversary. I need feedback ladies.... what should I do?
