I've had flu, then pneumonia and now I have a head cold. Yesterday i had a temp of 39, didn't want to move but had a hospital appointment for a scan. Was on the verge of cancelling when the meds kicked in and suddenly I managed to shower, dress, get a lift to and from my appointment and get what I needed done. Then I collapsed in bed again and still haven't left it barring toilet and tea! I've had a transplant so the most basic virus makes me really ill. So i hate people like your DH @crispysausagerolls because they make me ill like this by refusing to take sick days and going in ill!
All the doubters, meds can cause miraculous improvement on a temporary basis, thats what they're there for!
OP, my ex did this to me, he even tried to get me to pick DS up from nursery when i had swine flu and he was at home. He was so passive aggressive when i didnt go (I fell asleep) and the nursery rang because we were late. He tried to say to them i was just being lazy, but they had asked me to stay away when he forced me to do the morning drop off (he didn't believe me) and the nursery manager told him off over the phone! Of course,that was my fault too. He often left me to do everything myself, so in the end I said "fuck it" and left him.
The worst time was 5 years after we split. I was admitted to hospital because my transplant rejected. I asked him if, to minimise disruption to DS (then 8) he could stay in my house with him whilst i was in hospital (and I had to go miles away to a big hospital which was too far for visitors), and look after DS (who has SN), make sure he went to school and was ok generally. Ex refused, no real reason, just didnt want to. Thankfully my pensioner parents stepped up and did it all.
Shortly afterwards, ex fucked off for good and left the country. We've not seen him since. I was angry at him, DS has never forgiven him.
The amount of times ex emotionally abandoned me in our relationship meant i felt no real loss when i left him and then subsequently he left for good. It may sound dramatic to some to go straight to divorce, but you will be attuned to thus now. You will notice every time he refuses to support you and it will build and breed resentment. Hope you're able to look after yourself today. Unfortunately you're now stuck between a rock and a hard place because if you tell him your DM came over he'll see it as ok because you had help after all, and if you don't tell him he'll think youve coped fine and his behaviour was fine. Either way he'll feel vindicated in his actions.
