Moving together?

My boyfriend and I have been dating for about 5 months now and he wants me to move in with him. He says he’s lonely and sad without me. What’s the average time when couples move in together? He’s also struggling with some problems so I wanted him to fix those or at least work on them but he seems to think that he doesn’t have to if we’re not living together.

He has a big drinking problem and a drug problem and gets offended if told to get help. Yet he thinks he can do all that because he’s lonely and sad. He says he’ll stop if I’m with him. I have a disabled sibling that I take care of and he compares the two.
