DSS's mum has a history of mental health and has put herself and DSS in dangerous situations. Still has custody, shared with DH. She cycles and has periods of stability and instability.
Last night out of the blue I get a FB message from her sister asking for DH's number to have a chat or arrange for us to meet because she is concerned. I'm immediately sent both our numbers saying of course call anytime. Then went off to tell DH. He went nuts saying I was interfering and shouldn't have given out his details (or mine) AIBU? Was this wrong, I was just worried for DSS!
