Is this rude?

My sister in law (husband’s brother’s wife) gifted me a youth boys t shirt when she knows I’m super girly. It was size XL in boys and sleeves are short af doesn’t even fit. Literally for a preteen boy. And then she came to my gender reveal on Friday didn’t bring a gift. Next day was her son’s birthday and I took a gift anyways and she opened it in front of me and didn’t even say thank you. I know it’s not her kids fault which are my nephews by marriage but this really makes me not want to buy anything and give it to her ever again. I feel like when I give them something she also benefits because I always give them shoes clothes or $ so that in the end saves her $.
