Sex with ex??

So I recently broke up with my SO and the break up lead to us no longer living together of course. I plan on moving back home which is like 2 hours from where we were staying but not until May because I have to finish out the lease. We have come to terms and closure and decided it just isn't our time right now but we could remain friends or whatever. My question is would it be wrong to still sleep with him for the time being?
