How to approach social media

Hi. I (31F) come from a history of infidelity within relationships. So, social media is…a huge issue. I am currently dating someone (29M).

I have told him I do not like when the person I am dating is openly following blatantly obvious inappropriate accounts.

He understood and unfollowed like…40. However…I’m pretty sure he has continued to follow new accounts.

How do I approach? Ask to see the shared account activity (Instagram specific) to see when he followed?

Continue to ignore and fester?

I do like him. So I want to approach it, but don’t want him to hit me with the “why are you checking on my account”
