Need some advice

So started sleeping with a guy that I met recently on a night out. Chatted the whole night and got on really well. I added him on Facebook after we slept together and it said he was married. I clearly asked him about the situation and he said they were split. Anyway, Met him the next week for a drink and stayed over that night. After that, he contacted me a week and a half later asking what I was up to blah blah. Ended up seeing him again then after that haven’t heard from him. feel like I’ve been ghosted after the whole situation as I haven’t really heard from him. I still think he is married. As some signs point to yes. Should I text him and ask what the go is? Or just block and move on.
