Idk if this belongs here but I wanted some exredpill ppl to weigh in.

I(32f) just moved into my boyfriend(43m) of almost 2 years' house. He was gone yesterday and I was looking throgh his bookshelf when I found some old journals. Inside one of them were notes on a misogynistic PUA's lectures or something. Really disturbing stuff like alpha/beta bullshit, negging, etc. But what really disturbed me was his breakdown of women. Basically he says there are 3 types of women in his life: partners ("good girls that qualify as stable live-in mates. Kind, gentle, they are giving nurturers. I could have kids with this girl. She may or may not know about my crimes and mistresses and what I do on the road."), mistresses ("girls that I share a natural animal urge with. I want to envelop them and swallow them and absorb them completely for a short period of time then move on. These girls I would and should play games with. Play roles. Explore. Be uninhibited. These girls probably dont need to know about my partner. Don't get too involved with these girls. Don't commit. They might be crazy. Don't get attached. Always leave them wanting more.", and 3rd is partners in crime ("partners who know all of my secrets. They know about my crimes and mistresses. They participate in my crimes, artistic and otherwise. They are crazy like I am. I could have kids with her and she would be good to them. These are rare."

I don't know how to approach this. I'm wondering if he's had side girls/mistresses this entire time. I don't know if I should even bring it up because he might just lie to me, should i just plan on breaking up and moving out? I'm very trusting and chill by nature.. never look through his shit until now, I thought it would just be some poetry or something (he's a musician). I'm so disturbed and hurt. I know the answer is going to be to talk to him about it, but I just wanted to know what the kind ppl of reddit thought.
