MOTHERS DAY QUESTION..PLEASE READ!!!!!?

I know this is not the proper section for this, but the proper section is not answering this question, tthanks. Tell me who do you think is right, my girlfriends mother expected everyone to be over the house to eat by 2pm, im coming an hour away from church and i wont be on the highway until after 2, the mother doesnt really expect me to be there at that time, really she just wants the family to come over she doesnt mind me being there. I dont know the area very well, and my girlfirend felt bad for me, about me eating when i get there by myself and saw thet i was not even comfortable driving over there. So she asked her mom if it was ok that i drive to my girlfriends house, then from her house we would be on our way, she does not live to far. So really its only a couple of hours difference. The mother ends up blowing a gasket and saying all kinds of stuff like "this is my day, im suppose to come first" and stuff like that, and causing a really big fight between her, her mom and the father who was acting like the mediator. The mother was already upset over what was in my girlfriends refrigerator because there was some treats and stuff and concerned about my girlfriends weight, so she wants to be contolling over that. In the end, my girlfriend was going to go over at 2 anyway to please this woman, and then when i arrived at her house she would leave to pick me up and then we go back tio the mothers, i didnt want her to do all that, so i decided to just drive to her mothers eventhough i felt a little uneasy about it. Because of all this her mother deleted me off of facebook, which i see as very immature. I have done nothing to you. So the question is who is wrong, her mohter or me and my girlfriend. Thanks for reading.
