I [38M] feel insecure/jealous about my GF [32F] sexual/dating past.

So, we've been together 2 years, moved in together 3 months ago. So, while moving her stuff I cane across a box of her old photos of her from childhood...welp, curiosity killed the cat and in that box was an old journal...and I read through it.

At the back was a "list" and above it read "fucked". The list was 3 times as long as the partners Ive had (about 60 names). It had names of guys I've met, guys she said are her best friends, a married man over who is about 50+ years old, best friends and/or ex-guys shes dated who she has specifically said she never slept with. And it wasnt even complete cause she stopped adding to it maybe 5 years ago.
