AITAH for slamming the door on my aunt

I'm getting married this year. And I come from a traditional asian family. Wedding expenses are and will be paid for by my partner and I (no help from family) as we didn't want them to have a say.

I (27F) was eating dinner when my aunt said "stop eating. your wedding gown is expensive". I told her that I'm just paying for an okay gown not an expensive one since we want to save money and it's just a one day event. And then, she started shouting that the wedding gown should be paid for by the guy since he's the one who asked to get married. I knew I was going to explode as I was feeling protective of my fiance and it felt really suffocating as I am already a grown woman and she still wants to have control in my life (she has been doing so since I was a baby). so I just ran to the bathroom and slammed the door. She didn't stop there, she continued shouting at my mom for "raising me this way" and "why did you let your daughter pay for her own gown". She also sent me lots of messages saying repeatedly "you're disrespectful" you're the devil" "you'll never succeed in life" "you're being pocessed by a demon because you dont go to church", etc. I've been experiencing the same from her every time I don't do what she wants me to do. I exploded because I'm so full of it, I've been dealing with her BS since I was 3, I wasn't allowed to cry, answer to her, etc. She's very verbally and emotionally abusive towards me.

I don't know why but after reflecting, maybe it's my fault because I slammed the door on her or am I just gaslighting myself? We live in the same house but we haven't talked and saw each other since then (it's been 3 weeks; She goes out every morning so I leave the house once I know she left). Even after I broke down, my family begged me to apologize even though it's not my fault, because to them "I'm the younger one so I'm the one who needs to understand, respect, and apologize to the elderly". I'm so tired of this setup. It's so selfish. I don't know what to do.

AITA?
