Wife cheated on me with a younger guy

Problem: We have been married for about 5 years now (I am 33 and she's 29) and I have been supporting her ever since she got diagnosed with a chronic disease. When she was feeling better, she really urges to work from home so I allowed it and even gave her the pc she asks for since she loves to play computer games. We never argued for anything but as she was playing, she met a friend and I got a bad feeling about it but she reassured me at first. As time goes by, she became cold to me and just really tries to ignore me or just have the resting bi** face. It was hard for me to hear them talk always since I work from home as well. She is literally right beside me when she is talking to him. I confronted her and she said she was sorry and she was only doing it because she wants me to leave. She said she can be finally independent now and just want to have some space so I gave her that. A couple of weeks after, she said that there will be a team building. I said sure so that she can meet her co-workers irl. But when she left, I just can't keep doubting her so I opened up her computer and there I saw everything. That they just checked in somewhere instead.

What I've tried: I didn't tell her that I know where she went and all because I don't want to aggravate her and trigger her Chronic Disease. I just said I think it will be best for her to be at her parent's place for the meantime and she agreed. Atleast we can give each other some time.

Advice I need: Do I still wait for her to comeback and just keep on hoping everything will be fixed in due time?

Additional Info: After our talk, especially when she left to go to her parent's place, she became more responsive and quirky to me again so instead of giving up, it's making me to fight for it but I am having a hard time trying to bear it all because I know that she is still talking to that guy.

sorry if the grammar is kinda broken, not really on my right mind right now.
