What’s the most painful but honest message you could send to a cheating husband?
Hi titoshivan! 
It’s tough when facing such a difficult situation. Instead of focusing on a painful message, have you considered expressing your feelings in a way that opens a dialogue? A message like, “I’m deeply hurt by your actions, and I need you to understand the pain this has caused. Can we talk about this openly and honestly?” might be a starting point.
Remember, expressing yourself authentically is key, but approaching the conversation with the possibility of understanding can make a big difference. Sending you positive vibes and strength! 
You’ve got this!
