If I were you, I'd stop telling her for a while about the things that I found. People who cheat tend to lie about it. They seldom will tell the whole truth.
Keep in mind that most people who cheat are ashamed of their own behavior. So they don't want to answer the questions. They just want it to go away. It's a kind of self preservation.
When I found out that my husband was cheating, there were few things that he told me. Instead, if I found something out and confronted him, he would usually try to deny it. But if I had hard evidence he would eventually admit to what I found and nothing more. I eventually got sick and tired of this little game and gave him a choice. Either 1) he could tell me everything (I had a lot of evidence that I never showed him so I would know if he was lying) or 2) We'll just go with my imagination and it was probably worse than reality. I told him that I would make my decisions based on which path he chose. He decided that we'd go with whatever I imagined about his affair.
I also monitored him for a long time... years, to see if he would repeat cheat. But I seldom mentioned to him what I found. Thought I'd just let him prove himself or hang himself. He eventually hung himself.
It is normal for a betrayed spouse to ask questions about the affair for a very long time... 1 or 2 years at least. Why? Because it's a big secret. To re-build intimacy you have to 'own' the affair, meaning that you get to the point where you feel like you know enough about it that it's not some huge secret that she is holding back from you. Secrets kill marriages/relationships.
It sounds like you are telling her about everything you find as soon as you find it. Stop doing that. Every time you do this you give her warning to keep anything wrong that she is doing underground. Either she is being honest or she is not.
There is a good book that might help the two of you. It will give you a good idea of what each of you need to do to recover from the affair. How to Help Your Spouse Heal from Your Affair: A Compact Manual for the Unfaithful
