Should I move in with him?

How long should a person wait to move in with their significant other??

In September my boyfriend and I are going to make 2 years since we’ve been together and he’s talking about moving together soon when he comes back home in New York. He’s currently living in California for work.. I love him. I want to spend forever with him but I’m kind of scared. I guess it’s because anything I try to do on my own my mother makes it seem like I’m making the worst decision and would often say the phrase “ What would your father think?! Your father wouldn’t be too happy about this!”

My father died almost 2 years ago due to heart failure..

I love my mom and I wouldn’t mind staying under her roof more, but I’ve been sharing a room with my sister and brother since we were all born and my sister had a baby and my niece is also in the room now... my sister is 28, my niece is she’s 3 years old.

I just feel like I need my own space. My own privacy. The only time my boyfriend has ever came over to my house was when nobody was home. When I did try to bring him around when my family was home, my mom would complain and she’d come and open my room door and leave it wide open.

I am 21. I’ve never known what it felt like to breathe on my own. To have my own space.

Do you think it’s wise for me to move out?

UPDATE: I will not be moving in with my boyfriend instead my friend and I are looking for a place together. She understands my struggle she is currently going through it with her mother. This decision has caused a huge argument between my boyfriend and I, but we talked about it more and we’re fine. I had told my sister about my plans and she snitched and told my mom and they both told me they think I’m not ready and I kind of feel discouraged but it’s not necessarily stopping me.

Also thank you all for your input. I was very open minded to each and everyone of your opinions and I feel like I made a good decision.
