My ds moved out almost 3 years ago.
I thought we were close and he only moved an hour and a half away.
Obviously I missed him but got used to the quiet and rang each other every other week.
Last yr I visited him 3 times which was an achievement as I struggle with public transport and anxiety.
He came here twice.
It doesn't seem very much to me.
DD has bought a house lives 200 miles away and we see her about the same or less.
How often do you see dcs .yes I know they have their own lives.
