Should I out my narcissistic ex?

First off I know I shouldn't care but I do.

My narcissistic ex tends to be on social media in his designer clothes flashing lots of money. Meanwhile, he gave me hsv1 and hpv. Luckily I have only had 1 outbreak and it is otherwise under control.

Would it be wrong of me to out him on social media?

He seems so happy like he is doing great and part of me wants to try to burst his bubble. I don't understand how he can be so relaxed knowing he is spreading disease. Plus, I feel like he has ruined me and my chances at love with another man because I am diseased now.
