When do you move in with boyfriend?

I wanna know when you would move in with your boyfriend or significant other? I have been with my boyfriend for a year and 1 month and we have pretty big plans for the next year. Im about to be 21 in June and he’s 24. I want to move in with him as we got a place in our name already but i know my mother is from the caribbean so i feel like she wouldn’t approve or she’d make me wait until i was married to move in but I’m tired of living at home with my extended family and I feel like it’s too much to be at home with so many people in the house. I’m ready to leave and move on with my life. I just wanna know how long should you consider before living or moving in with your SO? Comment please!
