Am I wrong?

So me and my bf were having a conversation messaging, and he said he was trying to rest. I said ok then message me later. So about an hour later I see him online but he hasn’t said anything to me. Am I wrong for telling he’s fucked up cause he can tell me he’s trying to rest but can be online talking to other people . He says oh he just came online he was gonna msg me yea righhhttttt 😒😒
