Carly...welcome to a great place for support! I had text messages that could not be disputed - photos, etc. No question what was going on. I took those to a PI. He handed me a form to fill out. It was that process that made me realize that I was wasting my time and his. Questions like: what type of care does he drive, when does he leave for work, where is his office, yada yada. I was already 10 steps ahead of this process with the evidence I had. He gave me a free session after telling me that my evidence was 'g rated' - to me it was not! And that he could find more if I wanted, but what was my goal? He actually advised me to not out him b/c I may need to leverage what I have in the future. So I have not after 6 months told him HOW I know and all of WHAT I know. I don't know if/when I ever will. Right now he thinks that I found out about a specific affair from someone.
So my point is.....what if there is more? Do you need to know more? Or do you already know enough? AND....will you even get the truth if you get more evidence? In my case, I can almost imagine the stories that he would make up about each of the text messages. I could even hear him saying 'oh, this wasn't my iPad back then'.........it's amazing that the only person they are fooling is themselves. If he's a master at war - which mine is too - then save your sanity. Be thankful for your son. I have no children and carry bitterness b/c I gave up that notion to be with a closeted gay man for 10 years. I wasted the precious decade of my life only to find out it's a lie. Maybe your son can help you make a plan, once you have a plan, maybe you can get some movement and energy from your anger. Let us know!
