Should I move in with my old fwb?

We met off a dating app and hung out once no sex and then hooked up 5-6 times after. He had performance issues and by the end of it couldn’t finish. I stopped reaching out, as did he, and a month later he unsaved all of our messages. The next day he removed me. I removed him four days later and within the hour he had blocked me. Then he liked my story on instagram 3 weeks later and unfollowed me the next day. It was odd, but I chalked it up to him not being physically attracted to me.

I wasn't upset or anything, just figured it was what it was. We were never close either. Three weeks after he unfollowed me he sent me a message on instagram like " hey what's up", and unsent it right after. I then texted him, we made small talk, then he asked to be roommates.

In all honestly I need a roommate at the moment. He had been telling me about how he needed one a few months ago, so it's not out of nowhere. I'm also pretty sure we'd never hookup again so I don't think it'd be toxic like that. I think he's just not physically attracted to me at all, and we don't really have physical chemistry.
