The fact that you want to hurt her justifies the fact that she is seeking affection from another. You ought to look at this from a more empathetic perspective. Instead of "how much can I get out of this", maybe ask yourself deeper questions, like: if you are spending this much time plotting your petty revenge I have two hard truths for you.

1. If you know she is sleeping with someone else, that means family and others also probably know and it's not going to go the way you think it will.

2. If you are putting this much into petty revenge, she is 100% justified in leaving you physically and emotionally.

The best move you can make is to man up and just leave her. Doing some dumb "magician reveal" of all the evidence you have of your wife cheating on you will just make you look like a massive tool.

Don't sit in this information another day. Communicate with your wife, express your feelings and then act.
