But if he is cheating again, I am leaving. Also, I want to know because it gives me a better perspective of what is going on.
If repeated infidelity is a dealbreaker for you, then there's absolutely nothing wrong with finding out definitely once and for all whether he's re-established contact with his affair partner. It's only constant, obsessive "snooping" when you ALREADY KNOW EXACTLY WHAT'S GOING ON that can mess with your detachment (and even then I still advise people to get good intel, but to have a trusted friend monitor it for you and only give you updates as needed in order to protect you).
For the life of me, I'll never understand why people want to insist on flying thru the fog of adultery, without instruments.
