Creo que ya soy cornudo !!! Necesito consejos y opiniones!!!

Hello to all, I really need to tell you what's been happening to me for the past few days and I would appreciate it if someone who has gone through something similar could give me their advice. I'm going to tell you: my name is Juan, I'm from Montevideo, Uruguay, I'm 30 years old, I had several girlfriends throughout my life, but since I met my current partner, Sofia, two and a half years ago, she's 25 years old, really the ideal cutie, beautiful, intelligent, companion, funny, a fire in bed, as I'm 110% in love with her, and it seems like she is too. Less than a year ago, we decided to move together into an apartment that she had just bought, during the move I found out she had well-preserved a rubber toy shaped like a cock of considerable size, which surprised me but didn't annoy me, I just told her I would have liked it if she had shown it to me before, even so we could use it together, which she said she hadn't told me because she didn't know how I would take it. The truth is that on the same night when we had sex, we played with the consolator and even compared it to my cock, which is really not very big and this little guy was almost double mine, the truth is we passed bomb! So we started using it almost every night and began to get more perverse. One day during games with the consolator I confessed that her ex had given it to her as a gift, something that didn't please me much but I didn't say anything and kept going (I'll explain why I didn't like it later): Sofia was dating someone for over a year who was and still is the owner of the gym where she went, she left him four months before we met because he was very boring in the sense that he didn't like to go anywhere and also very jealous, surely the age difference influenced this energy difference (he's 42 years old), they ended on good terms even though she still goes there. That gym, I knew about that ex since we started dating and never worried because he would still be seeing her, didn't make me jealous, even though I recognize he's physically very good (not so much on the face haha) The question is after that day when Sofi told me about the gift from her ex, I started to worry and no longer liked it when she went to that gym, but I didn't say anything, started investigating something more about his ex and asked a friend who knew him because they had been university football teammates for a long time, what this friend told me was that this guy was very good people, but very serious, and quite womanizer, but what surprised me most was some data that left me even more nervous, is that this man was extremely well-endowed, according to my friend it was really impressive and the guy would walk around naked in the locker room without any kind of shame, showing his superiority to the rest of the teammates. From that moment on I couldn't get out of my head the image of my girlfriend and her big cock ex!!! Every time we had sex she would ask me to use the giant vibrator and it would give me a mix of excitement and anxiety that made me finish quickly almost every time!!! It was so much obsession that about two months ago she went on a weekend trip with her friends and I dedicated myself to searching among her belongings for any sign of contact with her ex, it was there where I found in one of the many files she had on her computer two photos of her ex, both photos clearly showed the attributes of this man (I clarify that those photos were from when they were together), that discovery generated a state of nervousness and anxiety that made me vomit in the bathroom, but what was weirdest is that after I finished I would feel remorse!!! The rest of the days I'd be machinating and thinking because my girlfriend still had the cock's photos of her ex and if the comforter made her remember it!!! Well, finally when I arrived she hugged me and felt that she loved me more than ever, that night we made love and used the comforter again, from then on I started to notice that she used the comforter very often alone (since she controlled where and how she left it and noticed that the next day it was in another place or position!!! I clarify she still goes to the gym every day from Monday to Friday (where she always sees her ex) and never notices anything strange when returning, although sometimes she comes back with other energy and that night I know it's going to be a fire in bed!!! Well, here I leave my first contribution and I'd like people to opine what I should do, say something??? Or keep quiet?? The truth is that I'm in a limbo between excitement and fear, fear of finding out something I don't know how I'll take it, fear of losing her because I feel she's the woman who fills me up in every sense!!!! I hope someone who has gone through something similar gives advice !!!
