I don’t want to be too outing, but in a nutshell, a woman doing casual babysitting for me at nights has cancelled last minute twice this week. Last night she said it was because her ex-DH had been drunk and violent towards their child, for the first time. She left her DH years ago because he was physically violent towards her but until now she’d never feared he would be violent to the children, and he still has the children 3 nights per week at his new home. She is a warm, kind person, and I realise how tough she is doing it (foreign country, no family around). She depends on ex-DH looking after the children these nights a week so she can earn cash from babysitting. I don’t know this person well enough to know if/how she is going to safeguard her children, if/whether I should offer support, if/whether I should report this, and if yes, to who? Do I just mind my own business?
