Just told a fuck boy to go away

A guy who I slept with once just messaged me. At first we're just catching up with each other. He tells me he's dating someone but he knows she's cheating on him. I tell him why doesn't he leave her. He said he doesn't really care, that he just wants to fuck. I see where he's starting to go with the conversation. I basically turn him down and that I'm tired of just being a piece of pussy to men. I think he got the message because he hasn't replied back
