I need opinions on family

This might be a long story but i just need some form of closure, help, advice, or something i. that nature of what to do. I turned 21 years old last year. My parents have always been one of the strictest of all of the friends i’ve had, to the point it’s almost embarrassing. I used to always have to be the first one home, i didn’t get to stay a friends unless my mom knew them, simple stuff like that. Well, now i’m dealing with being babies. I’m hoping there’s some moms on here around my mothers are (38) that can kind of steer me on what to do, or even people my age. I have a curfew of 11:45 weeknights and 12:45 weekdays. I don’t go to bars, I don’t go run around and do anything wild, I’m just constantly around my boyfriends family at his house because they help me be me without all my added social anxiety. I live under my parents roof, but I pay my car payment, my car insurance, my life insurance, my phone bill, cloths, any extra food i want. The only thing they pay for is the house bill and will give me gifts like today, an easter basket. I’m not allowed to stay at my boyfriends house, my mom doesn’t like me being over there when his parents are there but i feel like i’m getting a little old to be in that position. When i was 20 my mom wanted to talk to his mom to make sure she was at the house. My mom constantly questions me to death about everything and then makes me feel really low after. Even though I know she is i feel like shes never proud of me. I wanted to be a hairstylist, but she really isn’t supportive, other than helping my payments on school, she wanted me to go into nursing and is constantly trying to put doubts in my head even though this has been my dream job for 8+ years and i finally get to do it. i work quite a bit, as i’m in school 5 days a week. I don’t know to what extent i can handle being babied anymore and told what time to come home, being doubted about my career path and like nothing i’m doing is good enough. I’m scared to even tell her when and if i ever get engaged because i feel like she won’t be happy for me and will just put negative things into my head even though she knows my boyfriend is the glue that holds me together and she REALLY likes him, which is why i don’t understand why i can’t ever stay the night with him, stay at his house later or anything because she knows he is my protector, and if i’m going to town she wants him with me. i’m just wondering what kind of freedom i should have at this age, and with living with them, and to what kind of rules if you were my parents you would seek out for me. Thank you in advance.
