tldr: you say it’s getting better but it will probably get worse. Too many 🚩s to me. Cut her loose
🚩” So my gf stalked my ex somehow … She finally told me she found my ex’s yt channel and watched every single thing on there.”
So your current relationship went out of her way to deep dive into your past relationships? For what reason? Were you bragging about her? If not, this is some weird trust issues that your current “partner” has.
🚩” Now for the terrible part, smth i truly did not remember was that me and my ex had made a more personal video which was still saved somewhere on my laptop. I absolutely did not know of this and if I did I woulda gotten rid of it. Now my gf has access to my laptop (with my approval ofc) and she somehow stumbled upon it, I caught her curled up in my bed absolutely bawling her eyes out with the video playing on my desk. I have never felt this disgusting.”
A person digging into your personal items (especially a computer, phone) is unnecessary invasion of privacy. The erosion of trust has existed long before you and your current relationship met.
Your “approval” is only a formality. My bet is that if you didn’t “approve” then she would find a way to get past it.
🚩 “Now for the bad part and I cannot believe Im putting this online, we just had the most disturbing sex ever. It would be normal in any other circumstance but for the fact that it was almost entirely what the video wth my ex was. ”
In her mind, she will never live up to your ex despite you vocalizing the opposite.
Advice: cut her loose. This type of shit never goes away with time. The fact that she is emulating the adult video with your ex means she is competing with her. Despite what you tell her, in her mind she will never be enough. That jealousy never truly goes away. It may eventually turn into resentment or worse.
