I am off sick with the flu. Sadly the actual flu, not manflu looking at you DH . As in, can't get out of bed, sleeping about 16 hours a day, hacking cough, shivering, fever, the works. Am having brief interludes of feeling ok (usually when dosed up on various drugs) but am in no state to step outside, let alone get to work. Luckily have MN to distract 
Anyway, I came down with this on Sunday. My boss was abroad on business all day Monday, but rang on Monday night to say that he hoped I felt better soon and shouldn't even consider coming in until I felt better. Really lovely.
I emailed this morning to confirm I wouldn't be in again and received a lovely email back confirming email.
This evening he has called my mobile three times - 5pm, 7pm and 9pm. He left voicemails on the 5pm and 9pm calls. The first one was a reiteration of yesterday's vm, don't come in until better, we all miss you etc. The 9pm one said the same and he was worried not to have heard from me and could I call back to let him know I was alright? There's no suggestion this is anything to do with urgent work.
I live with DH which he is aware so no concern I'm on my own with turn for the worse or anything. I haven't picked up any of his calls because I've either been asleep or I'm awake but I have the sodding flu.
AIBU to think that I shouldn't have to call back and that 3 calls is excessive when he is aware I am ill?
So as not to drip feed, DH and I went on holiday this summer for one week and I received a text when I landed to say he hoped we got there safely. I then turned off my data (because, holiday) and when I got back I had 6 texts over the week, the last two asking me to contact him because he was 'very worried not to have heard from me'. He also frequently sends me chatty texts on the weekend letting me know what he's up to at home, which I usually 'forget' to text back to.
