Hi kelvin, I'm so sorry to hear what you are going through. I have been through similar situation except my ex husband was not at all honest at any point to come clean with his infidelity. Again he became my ex for a good reason as our relationship never had a strong foundation to start off with.
You are going through therapy now for 2 months? Perhaps give it more time before re evaluating the whole situation and how you feel again. I think it's really important that you try and give it time since the wounds are still raw. Again for your wife to come clean with you is also a bold step for her to admit to her mistakes, believe me not many people out there are capable of.
I don't condone infidelity in any committed relationships esp the most sacred marriage. But we are all human after all and sometimes things happen for a good reason? Perhaps a wake up call to many of us to what exactly is going on and what we can all do to improve the relationship?
