Relationship problem between dad/daughter and gf/gf

My gf is coming to see me after Christmas and she has to leave early for a dinner that her dad invited her to at his job that she doesn’t have to go to but she thinks that if she goes she will be making it up to him for missing thanksgiving (she only left the family for thanksgiving because her mom is a huge bitch to her and makes her feel like she was a mistake and a peace of shit so she wanted to get away from that) but so she is say that she wants to go to the dinner only because she wasn’t their for thanksgiving but she also says she wants to spend time with me. She say she doesn’t want to choose and hurt the ones she didn’t choose feelings and I told her me and her dad will still love her no matter the choice. And I feel really petty for saying this But yes I will still love her very much but she lives 3 hours from me and we only get to see each other maybe twice a year if we are lucky and I’m just saying it’s not like she sees her dad daily. I feel really bad for being petty it’s just. She barely talks to me. She leaves me alone for days and I’m ready for hours. I feel like she only texts me when she wants something, needs to complain, or wants to rant about how she doesn’t want to do dishes it some shit. I feel bad and. Idk thank you for letting me get this off my chest and thanks for taking the time to read if you did. Sorry for wasting your time.....

Update:

She going to her dads dinner I told her it was fine but now I feel really bad because I’m crying over her choice. It’s her dad I get it... I guess I’m just clinging. I’m the worst....
