Does my ex still like me??

So we broke up almost a month ago. At first I kept messaging him and begging him back. But I stopped around week 2 and today he's messaged me for the first time being really friendly. He's asked if I'm seeing anyone and he said that he doesn't like the idea of me having sex with another guy. But at first he was very clear that he wasn't interested in me and gave me blunt answers. But today hes lead the whole conversation- he doesn't normally do that. Does he still like me???

UPDATE: Turns out he was seeing another girl the whole time he was saying that he doesn't like the thought of me being with another guy. I dont know if shes a rebound or not? They were friends with eachother at first and he was the one who broke it up. Is she a rebound or is he moving on?
