UPDATE: MY SISTER FUCKED FIANCÉ

She's 19 years old! I'm 21 and my fiancé is 23. She always makes it seem like she doesn't think he's right for me and says she gets a bad feeling about him! This bitch was probably screwing him all along! I found out because she was texting him! He had it saved as Aaron and then when I see the messages it was clearly not a guy so I open the contact and it's my fuxking sisters phone number! He said she was so fucking sexy but dangerous. They also met up before while I was in class. She's in school too but online. He was supposedly at work that day. He said to her you felt amazing. She said you did too, this has to stop but it's so good. My blood is BOILING. This man proposed to me on Christmas in front of Abby (my sister) and my family! My mom dad and little brother (17). They all loved him except Abby. Now I feel like the only reason she was saying he was bad for me is because she wanted him. I called off our engagement. He lied so badly when I confronted him. He said that "you felt so good" was only a hug. He said they have flirted but never went that far. I don't believe him for shit! My sister said he's been coming on to her since we started dating. I'm like so why didn't you say anything and she said she didn't want to rain on my parade because o was so excited about him. Wtf type of bullshit is this? I don't even buy that anyways because she was raining on my parade by being negative and doubting him. Now fuxking him??!!!! She's a liar BIGTIME and him too. I've been crying all day and even in class today. Do y'all think it's possible that "you felt so good" was a hug??? Like my fiancé claims? They're both denying that it was sex

UPDATE: Wow! I am so thankful for all of the support you all have given me during this time. I have given myself a lot of time to really let the situation soak in. You have no idea how disgusted I am with my sister. Me and this girl have grown up together and encouraged each other. What she did was not loving. My stomach hurts every morning when I wake up when I think about what she did to me. It's not just her, of course! But her of all people. I'm literally so hurt like I was stabbed in the heart. Never in my life could I have sex with her bf/fiancé/husband/love interest/anything! I would NEVERRRR do that to her!! I can't believe it really happened. I've been thinking so hard about how was she moaning and how was he moaning. Were they thinking about me at all? Did they care how much this could hurt me?

First of all, it's confirmed that she fucked him. I went in her room and I looked her straight in her eyes. I'm like, "Abby, did you have sex with Daniel?" She said no but she was shaking and about to cry. I'm like okay so why are you getting so emotional and she's like I'm not. So I'm like wow you really did fuck him? I could see it in her body language that she was a lying bitch and she was ashamed of her nasty self.

I was like OUT OF ALL FUCKING PPL ABBY! MY FIANCÉ?!

This dumb bitch started blurting out excuses!! She was telling me that Daniel tells her that I talk shit about her and that I think I'm so much better than everyone. This is not true!! I'm not like that at all but even if I was, is that a pass to fuck my fiancé? I wanted to marry this CLOWN 🤡 and you opened your fucking pussy to him?

In my mind she's a dirty BITCH. I don't think I can forgive her. I just think of when we were kids and all that we went through together. I loved this girl more than I loved myself like my little sister was my world.

Right now you guys my world is completely upside down. I was reading your comments saying I should kick their asses lol but I just couldn't. I will feel like I'm fighting for him. I'm done. I want to get my own apartment and be away from my sister. She just looks like a snake to me now. I'm constantly staying away from her in the house but I can't see her face everyday. I'm looking for apartments with no waiting list. I'm ready to move in now. I know I can afford it and it's the best for my mental stability.

The pig 🐷 DANIEL will get his ass whooped by karma VERY SOON. I got all of my shit from him and all of my belongings back. He's mind blown and still denying it saying that Abby is jealous of us!! He's GENUINELY CRAZY AS HELL.

I'm like HELLOOOOO! She admitted it! Basically she admitted it when she started making excuses why!!

I'm so frustrated living with her but at the same time at least I'm done crying. I'm more furious than I am sad now. At first I felt sad like my possible husband was gone but now I'm glad. If he cheated on me during marriage I have no idea what I would do.

I'm going to update y'all soon! I really need this apartment and I really want to start fresh and find a guy that deserves me. But like I just don't want to get humiliated again. This was some crazy ass shit that I never saw happening to me. I'm going to get through though. And the support meant so much to me. Thank all of you!
