I normally hate the overly blunt and downright nutso relationship advice sometimes seen here(my husband left the toothpaste open again! DIVORCE NOW!)
But everyone is right on the money here, this guy I’m sorry to say isn’t even worth the electrons use to make and read this topic. He is just stringing you along so he has a chick on the side in case current GF ejects him from the bedroom, or to be cynical he is doing it so you won’t go file for child support.
