Dinner over Dick

Somebody please explain this logic to me or tell me if you agree. During an argument about my SINGLE friend casually hanging out with someone who offers to take her out (and has a few other females he also takes out), my husband says if she don't have feelings for him she's using him because if a guy is taking a girl out for dinner it's because he has feelings for her. But here's the point where I feel like he should shut the fuck up. He's cheated on me twice and claims he never had any kind of feelings for either girl. Now before you get stuck here yes he cheated yes I stayed and decided to work things out my choice really don't want all comments to be focused on omg why are you still married to him if he cheated twice. I have my reasons. What I'm looking for reaponses to is how is it giving a girl food is a show of having feelings but putting your dick in her means nothing. How in the holy fuck is that possible?
