I might be a bad wife…

So my husband is in the military and is deployed. We’ve been getting along the entire deployment and trusting one another. One day he was telling me how this girl from the country he was in really liked him and wanted to talk to him but he said he’s married. I didn’t think much of it but me being me decided to look at his Google photos. I do feel bad invading his privacy because we’re supposed to trust one another. When I looked at his gallery it was a picture of a woman’s hand giving him her phone number. Like why would he actually keep her number in his phone! I can’t bring anything up because then it’d be obvious that I looked through his stuff but apart of me is definitely upset. But I’m going to trust him…but if I find out he ends up cheating on me. Although this may seem immature but id prob cheat back. Maybe that’s just the anger in me talking lol
