Hi all any help would be appreciated, I am a truck driver by trade, and spend my week in my wagon so I usually pick my kids up on a Friday when I finnish work and drop them off on a sunday about 8pm but this week my ex said to pick them up on a Saturday about tea time so I did, apparently she was off work and wanted to take the kids out that's fine. When I picked them up my ex's mam was at the house and it was her who took the kids out because my ex was ither hung over or was ill, I didn't think much of it at the time I got the kids home my kids were saying they had a sore throat, I give them some calpol they were fine. In the morning they had a colff I give them a covid test and it came back positive, I live with my parents as I rent my house out due to the fact I'm away all week in the truck but my dad suffers from diabetes and cancer, I phoned my ex asking if I could take them back early as the covid test had come back positive and my mum and dad were due back from the caravan and wanted to make sure the house was clean for them getting in so my dad wasn't at risk, all I got was no you not bringing the kids back you will have to stay off work and isolate with them so now my dad's at risk, im off work isolating and my ex is refusing to take the kids back even though the kids have said there mam was poorly, and she started giving me a load of gip for doing a covid test on the kids and said it serves me right lol. Is there something I ain't getting here?
