Dating this guy and...

So I’ve been dating this guy since March and we’ve really clicked since the first date. However a few weeks after we started dating he asked about an older guy I dealt with. When I told him the guys age he got mad and brought it up 3 times. The last time he brought it up he called me outside of my name. A “hoe” to be specific. Since then I’ve stopped talking to him. He’s still been calling and texting me apologizing. I say all of this to say has anyone ever had a guy you really liked or loved call you outside of your name in that way? How would you have handled the situation?
