AIO if my gf lied about being freaky with other guys

Ok so long story short we are long distance, and she asked me for a dp, I didn’t send it but I was thinking about it, anyways later on she started asking me stuff abt being a virgin and stuff, and I ended up asking her if she ever got sent one or was freaky with anyone else? She said no, which confused me bc she knows a lot about sex and kinky stuff, so I asked if she’s ever watch corn, she says no? I asked if she’s ever read it, she also says no. So if she didn’t read it or see it anywhere where does she get it from…got curious and since im signed into her account, I scrolled to one of her “guy friends” chats and clicked it, it all seemed very normal until a year ago. Before this year they were freaky as fuck, like more than my relationship with her now, he sent her pics of shit constantly and she’d save it on her iPad. Bc they were view once. That was literally all their relationship was but I never knew bc she said she never dated him and he was just a friend, which seems to be true now. But I asked her about it again, and she straight up said she forgot about all of it.
I went through other chats after (ik I’m a red flag and most of her guy friends are calling her sexual names and being weird, by like “accidentally” sending her a freaky text at 3am multiple times or having inappropriate nicknames for her. She would just ignore it and not do anything with them (sometimes she would play along).

Now my heart is in my ass rn that’s why I’m posting this
Idk why I’m so bothered or if I have a right to be bothered, but AIO?
