My wife is having an affair with her boss

My wife and I have been married for ten years and we have four children. When we got married, she didn’t have a college education so I supported her through university and assisted her to get a job. She now makes double what I earn, so she was the one supporting our long-term projects. For some time now, I have been suspecting that she is having an affair. From my investigations, I have learned that she has been seeing her boss. She was two months pregnant last month and when I confronted her about the affair, she denied it and a few weeks later she had a miscarriage. I was sure the pregnancy was not mine. The affair is now confirmed and I just don’t know what to do. I don’t trust her and I don’t like that she works together with the man. She denies it but I have evidence. I am confused and feel betrayed. Please help.
