Old photo comments from his ex girlfriends... HELP?

[Kerstin Karen]

We're both 21 years old. We've been together for a year now. Here goes...

So we just got out of a fight today. And as I was browsing his facebook account, I saw that he still had the photo comments from his ex girlfriends dating from 2010 to 2011. And it hurt a lot to see that. So I decided to print screen it and post it in our private facebook group (just for the two of us)

So I have decision to DELETE the print screened photos of the comments, or let him read them again at least... it's just that I don't think it's fair that I got hurt and he doesn't know it.

Oh I and by ex-girlfriends, I mean 1. EX GIRLFRIEND, 2. EX-GIRLFRIEND 3. GIRL WHO HE USED TO CALL 'BABY' AND SHE CALLS HIM 'DADDY'. He claims that they didn't have anything, those were just pet names.

The thing is, we haven't heard anything from 1 and 2 for almost the duration of our relationship. Although the third is his friend in Viber.

What should I do? Where should I stand? I really need desperate help...
