So I was chatting up this dude for a little and he apparently is married I want to know if anyone else thinks I did the right thing or if I should of just blocked it and left it alone or what?

My question about if she was okay with it is because I'm polyamorus and wouldn't mind being a mistress if the wife was okay with it and it was some sort of short term thing. I know some couples get a mistress to help save their marrige I don't judge just trying to have fun but like I also don't wanna be a homewrecker.
