Thanks everyone.
So I was trying to get on with things and not worry about Mr. Runaway.
Typically when he's gone off on one of these benders he'll go to a hotel in [nearest big city] and I'll get a call from him saying where he is. Maybe asking me to cancel his bridge game or whatever. Usually castigating me for making him drink.
But still today no call. So reluctantly I had a quick look and his toothbrush is still here, his heart medications, his razor, his umbrella. His phone. It looks like he just put on his shoes and wandered out the door.
I looked at our bank account and there's a rather large cash withdrawal from this morning, made from [large faraway city with harbor].
I didn't want to make a police report, because in the past he's always been able to look after himself and he's always come home. But then I thought--just in the off chance something did go wrong I would never forgive myself if I didn't make a report.
So the police are sending a person round tonight to take a report.
