In need of advice

Me and my friend have been hooking up for about a year now. He now wants to start taking things more serious. However he is now starting to play the games of “ if didn’t answer because my phone wasn’t working” and so on. While I saw on his Facebook that he “got the best sleep and now is ready for he weekend😈”. Which does not make any sense on why he is posting if his phone is not working. I am very confused on why he is playing games and on how to leave him. Any advice?
