I like Van Damme. I follow him on social media and he seems to be good to fans. That said, its well documented that he's biopolar and that is pretty evident in the 'behind closed doors' reality show he did.
If I'm not mistaken, things with him and the wife have also not been great. She filed for divorce again last year so having the press constantly bring up a past affair when you're trying to reconcile would probably piss one off.
Celebrities are human too. In the grand scheme Van Damme has been pretty chill. Still, most people would kill to live the life these celebs do so they need to keep their shit in check.
