Drunk texts part 2

So the ex who was drunk texting me said he's completely done with everything to do with his ex, I don't know how to handle this, he kept talking about wanting to sleep with me, and I know it'll be bad for my mental health, but I also know I really want him, and I just keep thinking should I just do it or should I tell him I'm still not down for hookups and maybe talk to me when he'd be ready to actually be with me, or just tell him nothing is ever gonna happen again becaus he doesn't seem to be good for me
