Do I have the right to be annoyed..

I haven’t felt great the last week or so, cold/flu symptoms so I’ve been trying to rest, but I have a 5 year old with a horrible cough and a 1!year old with a sore throat and a night temp, my partner didn’t really help me when I wasn’t well, I’m not not fully better my body aches and Ive still got a cold and I feel exhausted. But this man has now got a cough and a cold and he has called in sick to work, has gone back to bed, so even though I’ve been feeling unwell all week and had to deal with the girls, he’s now ill and gets to go to bed and rest? And when I mention it and say I don’t feel great either he basically calls me a liar and says I have never mentioned it till now! I have but he is too busy going on about himself and how he feels crap to even notice that I have been unwell too but yet I’ve still had to do everything! I feel so angry towards him atm. I get that he is a bit unwell but so was I but I didn’t get to do what he is doing now. I think he milks it so much so he gets out of doing anything, now he has an excuse or something. Am I wrong or selfish to be thinking like this?
