BIL and his family live abroad. Me and DH ( it's his DB) live in UK and looking out for MIL falls to us, and to me for taking her to appointments. She's getting elderly now, and since Christmas has had some health issues needing return visits to the GP ( some GP visits I go with her) for referral for more tests, all of which I go with her for, she lives alone 25 miles from us. This week BIL was made aware by text and phone call that MIL had an invasive unpleasant hospital test being done this week. AIBU that he didn't ring before to wish her luck, or after to see how she was? On a selfish note from me, I would like an acknowledgement from him that I am taking her to these appointments, how about a "thanks for what you're doing for Mum'. I feel sorry for her too that she's not hearing from him. Grrrr.
