I am so sorry you had to see OW's truck. It's one thing to know on an intellectual level that something is going on, but quite another to be confronted with the harsh reality of it. When my H was actively involved with his A, there was every red flag in the world and I would tell myself that he was cheating on me. I *knew* it with every fiber of my being. But he vehemently denied it, and I couldn't prove it, so life just went on. When I finally saw undeniable proof, it was exactly as you described. I was literally sick.
Just know you are not alone in what you're going through, and it will get better.
I hope you were able to get some sleep last night and today is a better day for you.
