Okay I'll keep it short basically earlier on today I was upstairs sleeping with my daughter because I didn't feel well, my partner was downstairs, he was listening to the song beautiful girl by Sean Kingston.. recorded a snip of the song and sent a message to someone saying I listen to this when I miss you and the kids, initially I thought it was coming to me, but it didn't.. so I thought nothing of it and thought maybe his sister or something, it's been playing on my mind for hours I looked on his phone recently to make a call and there are no messages to his sister, just his friends and obviously it's not going to his friends.. now I'm paranoid if I mention it he's obviously going to deny and I can't prove anything either.. and it will more that likely cause an argument. So what would you do?
