Why do my parents want to control me at age 28?

Since I never got married , that’s y I’m 28 this month and still living with parents in a senior apt. Everyone got a perfect soulmate and married and I still never had a boyfriend that loves me.
I have one year in a tiny senior 1 bedroom apt size of a studio. I need my own room and bathroom, and asked my parents if we can move in to a 2 bed so I can have my own room, I want put a big sofa , big giant tv & my own business office corner as I have a small clothing store online & dream to re start it again.
but they refuse & don’t care of these dreams I have. The room is my moms room, I don't know y they expect me to just have no life forever. I can’t masterbate as they get home when I try. I can’t go out as she’ll get mad & don’t want me have sex yet I never have sex I have no boyfriend.
we fight daily & I work far so that’s only time I can run away and live in my car to avoid being home.
I cleaned her room & organized it 3 hours as she’s a hoarder & was a surprise for her & no thank u no hug, she don’t care.
she complains she wants me move up in life be rich yet when I’m sorta doing better or have savings she and dad get jelaous & not happy or try compete & say me too I also will get 2nd job.
they seem to like me be broke no sex & them controlling me.
I’m moving out demceber as I’ll finally have savings by then & by then my credit should go up as it was poor back then.
no cousins, no sisters, I’m alone in life & that’s y I want a warm loving boyfriend & be apart of his warm family & we have babies & my own happy home.
