Calling me when can’t get in touch with DH

FIL called me a few days ago. I was on the phone with the mortgage company. I called him back on the house phone, no answer. Then I called back on my cell once I got off because I though maybe he didn’t know the house phone number(we never use it). No answer no call back. I called DH and he said he waS calling him.

They used to do this a long time ago call me when they couldn’t get in touch with him. And then one day I said something so they stopped. It’s just sooo damn annoying. Like yes we’re husband and wife but we clearly have two different lives and I don’t track my husbands every move.
