Why don’t they send me a Christmas card

So I moved out of my parents hous last year before Christmas. I have now been living on my own for almost the past 2 years. My bf lives on his own an hour away. Well last year I thought it was weird that his mom didn’t send me a there family Christmas card photo but sent one to my parents but i figured with me moving she forgot and all. Well now she has my address and has sent me a bday card two months ago. My mom asked if I got his family’s card which again this year I said no and find kinda weird. My mom sent a card to my bf at his apartment and to his family. She doesn’t like me very much but I’m starting to think this is intentional when she wrote out my parents card she would have sent me there’s too. Opinions?
