Going to try not to yap this time but it’s long. I told her boyfriend yesterday with all the evidence, the nudes the texts everything. and hid my belongings. Everything everyone told me to do. I explained how she lied about my mom and I. How we both gave her chances and she kept him in the dark. I explained to him her victimizing and narcissistic behavior.

His reaction at first was saying he needed more evidence. He felt sick and like he gave her his life, it’s 8 years this year. It was clear he was going to break up with her and he thanked me, we wished each other well. But then he started asking me to message the other guy. I gave him the info he needed, saying he should contact him but he ended up just talking to her. I reminded him that she will do anything to get her way and to not let her get to his head.

Later he texted, making it apparent that she had chose the other guy. He said he just wants her to happy and if she wants to be with him, then let her. But then my sister got up, started slamming things, marched out the house in the night and texted my mom she was suicidal. I told my mom the truth and she seemed less angry than I thought. she said I did my part but was disappointed that my sister chose this other guy.

Her boyfriend was spam calling her but she wouldn’t answer anyone. So he connected to her ps account from his console and saw that the entire time, she was in a call with the other guy. So he joined the call on her account to talk to the guy to see if he can find out where she is. But everytime her boyfriend joined, kicking her out, the guy would leave the call. I asked him if there seemed like there was any way the other guy knew she was in a relationship the entire time based off of what he did get to talk to him about and he said no, that the guy seemed scared and very confused. But he got kicked out of the account entirely and she came home with the other dude on the phone. I have no idea what she said, but I’m assuming she got to the other dudes head.

Then, I guess her boyfriend changed his mind and decided to stay with her. They were talking it out on and off that entire night. He kept asking me to keep an eye on her and to tell him what she’s doing, but we all know her. she’s still lying. I told him she was on the phone with that guy and he was upset she didn’t call him instead. He said that he told her to block him on everything and she agreed. Obviously she didn’t? Then she told her bf she was in the shower, to continue talking to the other guy. I proved to him she wasn’t, and when he decided to call she ran to the bathroom to turn on the water and pretend she was. He asked me if I would let him know in the future if I see a sign of the other guy or anyone else. I said I would, but I explained to her bf that I won’t be around forever and a relationship that you need a third party to fill you in on their actions constantly, just doesn’t seem worth it. I did the right thing but that’s it, if you have to know what she’s doing every second then it’s clear you really should just leave her. like after everything she’s still lying to you.

but I guess she got to his head, too. 8 years is hard to let go of and at the end of the day he decided to trust her again. I think he’s too far manipulated. I don’t believe she blocked the other guy either because I have her account and she still has him as her profile picture.

so here’s the plot twist: I guess her “cheat back” story was true. Her boyfriend admitted to me that back in 2017-18 he texted other girls. But he said that was the extent of it and he never even imagined to do what my sister did. Since then he worked on bettering himself and has been loyal. I am in no way excusing him, but I also feel it doesn’t give her the right to do what she did either. She became like him and worse. Throughout this, my mother also told me that the reason why the family was so against my relationship was because my sister spread horrible lies about my boyfriend to everyone behind my back. It was her younger sister’s first relationship, and she watched my partner and I suffer.

Even if he stays with her, I’ve decided for myself personally to cut her off now. I’ve suffered a long time and I’m tired of walking on eggshells to simply “exist” to her. She’s narcissistic and manipulative, betrayed me multiple times, but what she put my partner and I through is my last straw. I thank everyone for their help, I don’t regret what I’ve done. I did the right thing and I’m proud of myself for not being walked over. I would inform anyone again, cheating is horrible. I thought my actions would help her realize that she can’t get away with everything, but both my mother treating her normally and her boyfriend deciding to stay and believe her lies seems to have undone that. I sincerely and deeply feel bad for both men and anyone who comes into her life in the future. for now, I seriously look forward to the day I can be free and have my own space.
