I, F27, come from a family of white-collar career people. My Dad 60M owns his own business and my mom 57F is a pediatric surgeon. My older brother M30 is a lawyer and loves to boast about how much money he makes. He is always buying new watches and expensive suits. He also drives a Porsche and is engaged to who will be his third wife.

I've always been more introverted than my brother and I tend to fade into the background. I created and operate my own business and make a more than decent living. My husband is a master electrician, and he owns a very successful business, he makes more than 3x what I do. We are a DINK couple (Double Income, No Kids); however, we keep our income very lowkey and don't spend money like my brother does. My parents are aware of how much my husband makes because we paid for their 35th wedding anniversary getaway and my dad saw the price tag.

We were at Mother's Day on Sunday, and both my brother and I bought nice things for our mother as gifts. He bought her jewelry and I got her a certificate for several hand massages at a spa near the hospital she works at. My mother thanked us, and my brother decided that it would be a good time to brag about how much the necklace cost, looking at my husband and joking about how he could never afford to buy a necklace like the one he got my mother. How my husband could never afford anything on an electrician's wage. He carried on like that until I had enough of him insulting my partner, who worked harder than my brother to get where he's at.

I yelled at my brother to shut up, and that my husband easily makes twice what he does and that he should sit his ass down and be more respectful. "Mother's Day is about mom, not you." were my exact words. After my brother left, soon after I snapped at him, I apologized to my mom, and we went on to have a wonderful dinner, where mom told my husband embarrassing stories about me when I was little.

My husband thanked me for standing up for him and my mom told me she had a lovely night while we were on the phone yesterday and told me she used some of the money on the certificate to get her wrists and fingers massaged after a 10 hour surgery, she told me she was very happy with my gift. My brother's fiancee sent me a tirade of texts blasting me for embarrassing him in front of our parents and calling me an asshole. I feel bad for causing drama but happy I stood up for my husband. AITA?
