you are going to get a lot of advice on this topic in this forum.
Try to take a deep breath and keep it together. This is just the beginning of a long process. Its extrememly emotional at the beginning.
My W also had an affair. He will lie to you and try to convince you were seeing ghosts.
I'm not the best at giving advice, but I fully support confronting him that you know he's having an affair. Thus, you should do some more investigating, but not let him know how you figured it out or what you actually know. Exposing to OWH will help and I think he deserves to know anyways.
Hang tough and be patient and let the advice roll in on this, it will.
