Overthinking or not?

Am I overthinking here? Bit of background my boyfriend was messaging other women a few months ago. He has a stand for his phone by the charger so he can watch YouTube ect but today he plugged the phone in to charge and purposely put the phone down with the screen facing inwards. He has never done this before. Is that odd? Or am I just overthinking? Personally I would never do that, seems like he just didn't want a notification/message to pop up and for me to see it. I need an outsiders view here 🙃

Yes it is embarrassing but we have four children together so I was hoping we could make things work.
