Tough road starting over

Hi folks, I hope everyone is in a good place. I left her over a year ago. I filed for divorce 7 months ago. I moved away and found a new job. A great position and I am happy about my career. My 16 YO son is far from me and it was he who told me when I hesitated taking the job so far from him. He is so mature, he told me to go for it. His mother betrayed me badly. So badly it robbed me of my self esteem and literally my soul. Never in a trillion years would I have thought she would a be capable of what she did. This has been the hardest thing I have ever experienced. Looking back, after nearly 20 years together, I can see it was not an isolated incident and there could or was many times with different men. She still denies it. I told her that she was willing to continue to lie and destroy our family just to save her image and ego. It was with her boss, I confronted him —non violent and told his wife as well before I filed for divorce. It has been 3 years actually since I caught her and I still have some bad days. I hope everyone recovers.
