Generally you don't stay in touch with an ex at all unless you have to for some reason like already having children together.
I think him saying he needs space is just code for saying fuck off but he's too nice to put it that way straight out.

i don't think being friends with an ex is hardly ever a good thing. if he's not talking to you, then jsut leave him be and move on. when he wants to talk to you he will... if he decides not to talk to you again, then you probably dodged a bullet... you'll find someone better :)
