They are split up and she is worried that dad is going to hear about whats going on. All she can do is social distance and do drop offs as school not responded. If you are meant to self isolate u cant even leave house , so being in car same as being outside school gates from everyone.
Basically mum and dad dont get on great so he need not know as self isolation period soon be over and lockdown lifted for this month thank goodness/
Also please note con1 they are going through family court proceedings where she is concerned about if ex finds out it will be used against her. It wont as school ignored emails on more than one occasion so she was obligated to take daughter to school with son present socially distancing from everyone
