Ladies I feel empty sometimes

So sometimes I feel I’m on my own. I wish I could tell my mom everything but it’s just not gonna happen. I know maybe my mom tells me some things because she cares for me but it’s just hard not being able to talk to anyone. So she doesn’t really like my bf and he gave me some roses and like a basket of like some makeup that her sister made out and a couple of items also some 10k gold earrings and a rose that lasts for a long time and then my mom sees the makeup and starts telling me he’s not taking me seriously and to start getting away from him because he gives me” cheap” stuff and I give him good gifts. Then she’s tells me to tell her absolutely everything he tells me and I believe that it’s a personal relationship and I don’t really have to tell her that much you know.. Also it gets so annoying my brothers are always trying to take my phone away just to see the messages I have with my bf. I literally have no personal space. And the times I go out with my bf it’s only like once a week and I have to literally tell her and then she’s calling me two hours later to go home already like I can’t even spend the time I want with him and my bf wants to meet my parents and my mom just doesn’t want too. I feel so sad over this because I feel I’m not enjoying my time as I would like too. It’s not fair for my brothers to go out at night and I can’t do that. It sucks how I get treated like a little girl when I’m not already. I’m 20 I’m not that old either but I know what’s right and what’s Wrong. I just wish I had a different type of lifestyle
