Concern??

Hello mommies I just need some advice on how to approach this. I’m currently 2 weeks postpartum with my first baby. Well recently I came back home to stay with my parents for the 40 days. My boyfriend is staying with me. Well I noticed that he’s been stuck to his phone. I have been emotional and wanna know if I’m over reacting. He’s been like stuck to it. On it a lot more. When he goes to the restroom, showers, steps out, goes to sleep and puts it next to him too. Well I noticed his phone goes off for snap late, and early when he’s about to wake up. He said it’s the guys messaging him. But honestly it feels a little off. Last night I laid next to him after putting the baby down and he went into an app and typed in a code. He seen that I seen him and just scrolled then looked at me and put to the side of him. It just seems off. Am I overreacting.
