My mom gaslighting me

Ok i’m 24 a week away from graduating nursing school. I’m dating this guy for about a year and a half. He’s really nice and it’s a healthy relationship. However, my mom has been acting like…. I don’t even have the word for it… all I can think is jealous??

For example, he bought me a starbucks drink bc it was my last day yesterday and I just told my mom and she’s like “oh why doesn’t he go pay ur fucking tuition then?” like huh????? i’m also sleeping in listening to music rn and she’s like “why don’t u do that when he’s here huh??” like she’s acting so weird and mean… she was never like this when I was depressed. I lowkey feel like she liked when I was sad and alone. even since I ended school she’s like freaking out that i’m gonna be selfish and absorbed into my own world… like wtf….. she’s not this hard on my brother at all. this is a super happy time, i’m graduating from nursing school and she’s acting so mad and angry. I can’t even share anything nice that my bf has done otherwise she’ll get mad. one time he got me flowers and she was mad and said they’re ugly. another time he ordered me a starbucks for passing my last exam and she was mad he didn’t get her anything. it’s really really weird and i’m so sick of this. and then she complains why I don’t wanna spend time with her. or she’ll throw how much money she’s spent on me to my face. she would also k word me if I wanted to move out. I love my mom and want a nice relationship with her but I feel like she’s been kinda toxic lately. I made the mistake of telling her that I love him and she flipped out saying love isn’t even real and relationships at this age don’t last…..

all her friends literally brag about their daughters and I feel like she’s always telling people my faults. I just can’t take it
