No Bra

Am I in the wrong for getting up this morning and going to the kitchen with no bra?

My sister in laws bf got here last night after being at work for 21 days and I thought he would still be sleeping so I was doing my normal routine and hadn't put on a bra. Next thing I know he's out in the kitchen making coffee. So we chatted a minute and I picked up the cat to hide I wasnt wearing a bra.

Well next thing you know my bf is mad that I didn't wear one while in the kitchen for those couple minutes. I was shocked. Like I wasnt trying to flash my tits around. Not only that I always make sure to wear a bra and be respectful when my sister in laws bf is here. I'm upset my bf is making me defend myself as if I'm a bad person for this.

Somewhat worried he's gaslighting me because he's looking at models online again... thanks for reading my vent..
