I’m just curious,

My husband and I are going through so tough times and we were arguing about an app he had on his phone, nothing bad just an app that was causing issues and he thought it was normal to download the app when at work and delete it when home. So to make him understand how stupid that sounds I said fine I’ll just download dating apps while you’re gone and delete it when you’re home and he said fine I wouldn’t care…. Does this sound normal? I told him if that was true we’d be done because how does a husband not care his wife is on a dating app right?
