Why is my mom so emotionally manipulative?

im 23 years old, getting my second bachelors degree and i would like to spend my first birthday and Christmas away from home and with my boyfriend and his family this year instead, i thought it’d be very nice. we’ve been dating for almost 7 months now.

but when my mom heard about how i was coming home the 26th instead of the 25th, she became so emotionally manipulative and started guilt tripping me. saying things like “you need to fly back on the 24th or come back the 25th, “right now it’s family time”, “oh so you don’t want to spend Christmas with us, everyone does it” and even blames me for coming back home for Thanksgiving for a work event and not to spend time with them. then proceeds to hang up the phone by saying “whatever you booked the flight already, whatever”

i’ve spent every Christmas growing up with them, and honestly we don’t even celebrate the holiday.

how do you deal with this? i don’t want to end up having to cut relations with her but how can i go about this? i feel like the only way is to just keep my distance and argue
