What does everyone think

My other half has been so different lately not cuddly nothing not a kiss don’t sleep in the same bed just absolutely nothing. I’m pregnant with our second and today I look over at him his got his hands down his trousers smiling at his phone. I asked who he is talking to and he said it’s a friend but I don’t know my gut saying different. He won’t let me look at his phone. I don’t know his passwords his changed it. What do you guys think
