was i wrong

so since i got back from the nail salon my baby father has been acting weird as usual I had laid beside him he's set up and then continue the text now the way he holds his phone is that he will tell the towards him so he can only see it what makes me think of something else going on so I was cooking just a few minutes ago every time I came back in the room he would get off his phone when I got close to him as I gave him his plate he was texting but then he closes phone so I just texted him saying that he's on some sneaky s*** he says hes not but i dont trust him
