<human>: Condense the text into a few key points

I don't have the greatest relationship history.  I've been in relationships where men have used me for sex/money/to fill their time and then kicked me to the curb when they've gotten whatever they want out of me.  I've had emotionally abusive relationships where my SO at the time has put me down, called me derogatory terms, manipulated me into believing things were my fault, etc, etc, the list goes on.

My current SO is generally wonderful, we've been together for a year, and he treats me better than any man ever has.  However, there are times when we'll get into an argument/heated discussion, or I'll do something, that will cause him to speak to me in a derogatory way.  He'll call me crazy, ridiculous, terrible, etc.

Even if there are times when he's being sarcastic or using a joking tone, my history with men using those words towards me makes his use of them cut deep.  There are emotional scars and wounds I have that may never fully heal.  Every time I try to tell him that I'm not ok with him using those words towards me, he'll tell me that I am overreacting and that I need to chill out.

I don't think I'm going too far when I say that I'm not ok with being talked to that way.  I will **never**, *ever* be ok with a man calling me crazy.  How do I help him understand that being treated that way, regardless of intention, will never be something I'm alright with?
<bot>: My current SO thinks it's ok to call me derogatory words, and that opens up old wounds.  I can't get him to understand why I'm not alright with that.
