When is it a good time to live with your boyfriend

Mandi • I’m a fashionable, artistic, nerd 😉
Me and my boyfriend been long distance for nearly a year and me and him kinda talked about living together  but we didn't finalize anything about living together yet it was mostly talking about it. When do you think it's a good time to move in with your boyfriend? And please no negative comments I know people who had bad break ups living together but I also do know someone living with their boyfriend can last forever.
