Hi Jay
Your situation does not sound fair at all and would drive me insane. Whilst this is no time for point scoring, you and your ex do need to agree, and stick to, a set of guidelines that will keep all of you as safe and well as possible.
I think I’d start with a conversation with your ex about the situation, establishing, that at the heart of this is, the need to keep everyone as safe as possible.
Also I have been in lockdown with my trio for 6 weeks now and it is such a struggle. Not only do I work full time but I also now feel called upon to be everyone’s counsellor, teacher, best friend, games partner etc etc And I cannot manage it all! So I am sure that your kids (and your ex) would be grateful for as much face timing and support by phone, email as you can manage as well. You will never be on the outside.
Hope things get sorted.
