Am I the a-hole in this situation?

Okay so for context- boyfriend and I are both 25. Boyfriend has been having gastrointestinal flare ups every ~2 months or so. The flare ups last for about 2 days and then go away. He has a scope scheduled next month to try to figure out what’s going on. Symptoms include vomiting, nausea, stomach pain, etc.

Boyfriend started new job in November. This is his first real job, he wasn’t working before due to mental health.

Boyfriend was sick with the flare up Saturday and Sunday. He couldn’t eat for 2 days. By Sunday evening (yesterday), symptoms started to go away. They are completely gone now. He works 3rd shift so he wouldn’t have had to leave for work until 4:00pm today (Monday).

He has decided to call off work today. He already has 5.5 occurrences for missing work and if he gets to 9 he is fired. We are only in May and the occurrences start over again January 1st.

My thought process is, if he’s feeling completely better why not go to work today and miss work when symptoms are actually active. I’m afraid he’s going to get fired. He also hasn’t saved up any PTO because he’s missed work so frequently. He missed work for mental health reasons 2 weeks ago.

Last night when he told me he was going to call off today, I said “why miss work if you are feeling better? I am afraid you are going to get fired.” My boyfriend got extremely angry at that and started yelling at me. He said he needed me to validate him and that if the tables were turned and I was sick all weekend and then told him I needed a day off, he would encourage it. The difference is that I don’t have any points racked up, I barely miss work even when I’m sick, and I have a ton of PTO saved up.

Once he started to get angry I told him it’s okay, I was just asking a question. I didn’t push it. He continued to be angry for awhile. We do share a bank account, share all of our money, and are saving up to get a house.

Am I wrong?
