Okay so three days ago I decided to end it all but in my own terms, I called the brother over and got him to send me the video he had of my bf with his ex, then we proceeded to hook up and I took a video myself (this part is editted as many people have pointed towards it looking like it is a sextape and it is not, in the video I took we are JUST kissing, fully clothed and standing up, the video was prior to sex). I asked him if it was okay to send it to my bf and he said he didn't mind, as he couldn't be kicked out of the house they share because their parents are paying for it.

After sending him the videos I blocked him everywhere. I also told the brother I was not interested in keeping hooking up with him and we could stay as friends if he wanted, he said it's okay and it was fun even if it was over and agreed to the friends part.

Two days ago my EX tried to contact my friends and my parents asking about me, I had told them the relationship was over in bad terms and not to tell him anything about me, in the meantime I was staying with one of my friends for a few days (I knew he'd try to contact me). That night I had to work (I am a nurse in the ER) and he appeared there at 3am yelling and demanding to talk to me, I called security on him and talked to the chief nurse as I almost got into trouble.

Yesterday the brother contacted me and told me that they had had a huge argument as predicted but nothing else happened. He also told me the ex came over to the house and they also got into an argument (yes, walls are paper thin, that's why we always came to my house) because he wanted to stop seeing her to try pursuing me to take him back to which she answered that he wouldn't be able to do that as she was 2 months pregnant and she didn't want an abortion. So yes, I was being cheated on for more time than I thought, now it's all over and he's still trying to contact me 🤦🏻‍♀️

Thanks for all the advice you gave me, I appreciate it and you were right, that relationship was going nowhere.
