My girlfriend and I are in a long lasting relationship. We live together, have a kid on the way, the whole shebang.

She is very close with her exes parents. They are the grandparents of their daughter. They take the two of them on vacations with them, include them to social dinners, etc. 

She and her ex were “on and off” over a long time. Roughly since high school. Their last breakup was over 3 years ago, and they’ve both dated other people since. She, however, maintained her relationship with them for her daughters sake.

She is asking me to essentially befriend them in the same manner as her. I have no issue with this, I will come around in my own time. They are after all, the grandparents of her daughter who I care very much about.

My dilemma is that I don’t know them well enough yet. I’ve eaten dinner with them once. And now I’m being asked to spend Christmas with them, and her ex who will also be there.

I am not insecure about her and her ex, but I am uncomfortable in this particular scenario. Here you have his mom, his dad, his daughter, his childhood home, his ex, his current girlfriend, and I just feel.. like I don’t belong there.

I don’t know any of them, and I don’t really want to spend Christmas there because it would make me uncomfortable. 

Am I being an asshole? I just can’t see myself sitting at the table with her ex and his family asking them to pass the butter.
