I think you dodged a bullet as it’s best not to
Get involved with a woman who is married and clearly was looking to find someone to fool around with. This could have ended up being a disaster and could have created problems with your work.

This woman has decided to cheat on her husband. Not the kind of person you want to get involved with. When someone shows you who they are BELIEVE them.

Just be you, a wiser you. You can be nice and just move forward grateful that you dodged a bullet.
