He deleted it before I could see it.

I have already trust issues in the past with my husband but we moved past it. Of course that trust issues can come back. Well me & him have the same phone. I picked up what I thought was my phone, turned on the power button, because we both have different screen savers. Well the first thing I see is a text message from a 600 number saying 'hi bb can I see you rn'. My ass is like who the hell is this?? He says it's a wrong number. And I asked him to let me see but he straight up deleted it in front of me. Thoughts? I want to give him benefit of the doubt. But seriously I asked to see it. He heard me. But deleted it anyway. Even if It is a wrong number. Thats fishy. Right? Or is it just all of me because of course I'm overthinking it.
