Quick background. Ohs ex left him in 2010 taking their dd with her. In 2012 she met someone new and I got together with oh. Me and my kids moved in with him (we were living far too far apart prior to this). We were having his dd over eow plus extra as she was going away long weekends with the new bloke. There have been issues with the kids but we were working them out.
Last year ex moved in with the new bf taking dd with her and also my ohs oldest dd. Oldest is still there but mainly living with her bf. Youngest (age 11 nearly 12) was taken out of school here and is now settling into her new school. Contact has been drastically reduced. We are on esa due to oh being in a bad accident and we don't have the money to drive 160 miles eow to do pick up and drop off twice. So it's mainly holidays now although last holidays oh asked for the whole week and got given three days ...his dd was actually at various friends and relatives and we got the last three so we could drive her home.
About a month ago his ex told him she is ill. She has cancer. Oh bumped into her bf at the hospital today and found out ex has been in for the last week and she's not reacting to drugs. This was at 2.45 and an hour's drive from their home so I don't know who is looking out for dd?
Should oh try and talk to ex bearing in mind she says it's nothing to do with him. Should he be doing anything? I am loathe to suggest a ro unless it's essential but it's worrying that ex is not able to care for dd and her bf has brain damage which causes memory loss and he can't cope with stress.
Really would appreciate any suggestions at all or ways oh could talk with dd about this. They are still married too.
