I found the email on my husbands phone that was from Craigslist secret code. He was caught cheating last year and now I am finding all these dating sites on his phone can you please help me What is it for?

"What is it for?" What is what for? I imagine it's for dating. What do you need help with? How to get a divorce? Why are you on his phone? He has cheated, and you don't trust him so you snoop. The marriage is doomed. You might as well leave now, or try to kick him out if you have children.
