Suspicious?

So Sunday I spent the night at my parents with our baby he tells me he was going to sleep at 10:30 but his messages were still delivering they don’t when he’s not on his phone so I checked his Instagram he sent this girl he knows a message at 12:52 am shit whoops. Sorry. And then he replied to this group he’s in at 3:40 am he didn’t even reply to the messages I sent him....
