Bruh. He's winding me up

He's usually super easy to deal with and get along with. My ex baby daddy. And I know some people freak when the term baby daddy is used but we are civil and I call him that all the time. We were a 3 night stand who got pregnant, tried to make it work for a minute and went our separate ways by the time I was 4 months along. We reconnected (civilly) about a month before I gave birth and there's no court nonsense. It's his choice - seeing our kiddo on average once a month - I've always been open with the exception of one thing - no visits when you're sick.

Our kiddo was a preemie with heart issues and downs syndrome and a trach - very much so special needs and medically complex so the only rule I ever implemented was no visits when you're sick (also anyone in your household or if you were around sick people just wait a few days and make sure you're good type of thing).

He has been decent. I dont need him in our lives he is respectful and every month he sends or brings money without me having ever asked. We are civil. And for the record again I wanna make it clear that my door is open to him and him coming around once a month is his choice - he lives far and works stupid long days and gets one weekend off a month which is when he sees our kiddo. No issues. Sometimes he will spend the night in town at the hotel to get two visits in a row.

Anyways here is the concern.

He tested positive less than a week ago. Not vaxxed or anything which is whatever his choice. The issue is he tested positive and still wants to see our child this coming weekend.

I said no way for that reason and for the first time hell broke lose. Am I unreasonable here?!?!?!?!
