Please Help Me Figure This Out



So I'm 30 this weekend, and I currently suffer borderline personality disorder. It's caused me to see the world very differently and some things that seem trivial can upset me so easily. Here's an example I'd like your opinion on.

My husband and I are playing badminton. I say whoever wins next has to do the washing up the next day. He says "Well I do the washing up anyway" which offends me because he doesn't ask me to do it. He's normally already done it. Should I be as mad as I am about this?
