Advice on possible EA

[Greek]

Do I confront her with evidence that she has been making contact and that I know that she is lying to me about things and it is not acceptable.
Or doI bide my time until I have concrete proof because at the moment I dont have any proof that she is having an A with anyone, although I do consider her relationship with her work friend an EA.
I would really appreciate some input on this one. Thanks

"W, your contact with these other men is inappropriate for a married woman, destructive to our relationship and disrespectful to me. I want to work on making our M better for both of us - I want to be a better husband to you - and I want you to be a better wife to me. In order for me to go forward in a M with you, you will have to stop contact with these two other men and be transparent about it. If you are not willing to do that, I will take steps to protect myself."

Let her answer.
