My Ex Is Moving Back To Town Do I Tell My Man – Leo and Rebecca Buzz Question

Leo and Rebecca Buzz Question - MY EX is moving back to town..do I tell my man? He's been gone about 5 years and I found out from a girlfriend that he's moving back. It would be no big deal, but my man thinks he lives in another state and they had issues way back. I just want to know if I should give him the heads up?
