Is this wrong of my mother? PLEASE HELP ?

I invited my mother a few weeks ago to come to my apartment for an Xmas dinner - I told her it would need to be before Xmas so around the 21st and she said yes she would come - and then said why did I spend the Christmas before last year at dinner with a close family friends family instead of her and her boyfriend (who sexually harassed me and tried to bribe me but that’s another story) when she had never invited me in the first place.

Anyway my mother is currently not working and sits in the car with her controlling boyfriend whilst he couriers deliveries to random locations in the city - but she never does any of the work other than sitting in the car and helping to lift things. Anyway I live alone and had made a big pre order Xmas food delivery of lots of nice Xmas foods I thought we could enjoy together, as well as decorating my new apartment really nice and buying a big table and chairs so we could sit and eat.

I told her yesterday if it would be okay for her to come on Monday afternoon as that’s the day the food will be delivered (in the morning) and she said no she will be working (by that she means sitting in her husbands old van which she loves doing because she is obsessed with him even though he gets drunk and hits her and had a record for gang rape) and I told her but you said you would be able to get the day off? She said no she couldn’t, but she can come at 8pm at night and stay for 25 minuthen leave, after I would have spent all day cooking for her?
