So my immediate family has been very avoidant of my girlfriend of nearly 6 years

I wanted her to come to a family Christmas consisting of me, my mom, my dad, and my brother

My mom was strongly against it. Since my mom has a history of this my gf really wanted me to give her the ultimatum of she comes or neither of us come

I really don’t want to rock the boat because well I want to have Christmas and I’m also going on a several day road trip with them and I really don’t want to have that on top of everything else And of course my mom guilt tripped me a bunch too cause she’s been dealing with her own flurry of problems

As I’m writing this I’m leaning towards standing up for my gf I’m just really frustrated and honesty just wanted to vent

I’m mostly just don’t want to ruin Christmas and I just overall feel like I’m being a problem
