Bf’s mom crops me out the photo

Do you think it’s rude that my bf’s mom takes our photos from Facebook, crops me out of it, and just posts the pic of him???

She has always been nice to me and I thought she liked me. But I’ve noticed on her social media, whenever she posts pics of him, she crops me out of the photo.

His other family members had made b-day posts for him, and posted pics that has me in it as well. But not his mom lol.

He has pictures of just him, so I don’t know why she doesn’t just use those.

Any thoughts ??? lol
