Is it Normal that my parents are this controlling?

yeah my parents were really strict on me too. i was never allowed a boyfriend and had to be home at a reasonable hour. they tried to tell me to not be friends with certain people because they didnt like them. my dad used to hit me a lot, even just for being on the phone with a friend for two minutes too long. i lied to my parents all the time about who i was with and where i was going.

but when i grew up and matured a little bit, got a part time job, they started to respect me and lifted a lot of the rules they put on me.

now that i am married and trying to start a family of my own, i understand where they were coming from, they just wanted to protect me and make sure nothing bad happened to me.

you didnt mention in your post if you work or not. maybe you arent showing the maturity of a 23 year old so they still see you as their rebellious teenager. try showing responsibility and maturity and see if that changes how they treat you.
