Forgetting the past

How do you let go of your boyfriends past? He says I’m the only body he’s seen. But I dug into his email and saw someone emailed him pictures of their vagina like 6 years ago. I know he blocked the email when we first started dating. Do you think he sext her or something. How to stop? He has bad memory so he probably forgot. How do I forget? How do I get over it? Ik u shouldn’t dig if you don’t want to find but I did. I wanted to know 4 some reason.
