Need advice & please be kind. My husband cheated on me a couple years ago…?

My husband cheated on me with prostitutes a couple years ago. We have worked hard through our issues & are still together and doing great. But i have my moments. I still have all the evidence (text and phone numbers) saved on my phone. At times I find myself go back through them. I’m not sure why. Should I go ahead and delete it all? Or is that something I need to keep?
