Would you be concerned with your husband going to bars?

My husband recent got a promotion at work. With the promotion also comes some occasional traveling. For the past 6 months he has had to fly out of state once a month for a 3-4 day business days.

EVERY SINGLE TIME he travels out of state for work he goes MIA after working hours (after 6pm). I call- no response. I text- no response. We have kids and they always want to say good night to him but I can NEVER get a hold of him. (Literally for the past 6 months he as only FaceTimed the kids TWICE to say good night out of 20+ possible nights)

When I ask him the next day why he didn’t answer my calls or texts he usually says that he just orders dinner in his hotel room and passes out.

Come to find out- he is actually either spending his evenings in the hotel bar, or going to a local bar within walking distance of his hotels.

This is concerning to me.

I have no evidence of any cheating. And when I try to talk to him about it he shuts down the conversation. I can’t get anything from him.

If this was your husband would you be concerned? Or would you have confidence and trust enough to just let it be?
