My sister is the worse person I have ever met and I think I hate her

I don’t think I have ever met a more vile, self absorbed person in my life. I could make a list of the things she has done to me but I don’t even care about that right now. We both have cats. I love mine, he’s my baby. I love hers too, I consider her my own. They will both have been with us for 5 years in a few weeks. Yesterday she abandoned her. Left her out in the middle of no where apparently. She was such a sweet girl. She wasn’t very cuddly, but she showed affection in her own way. My sister didn’t like that. She wanted her to cuddle her like mine does me. You know what tipped the scales today? The cat wanted to go outside and didn’t come back in when she tried to get her. So she brought her to what she called the middle of no where and left her there. She told me about it so I wouldn’t be looking for her and talked about what she didn’t like it was the most mundane thing in the world. Like she was bringing the trash out. My poor baby.This isn’t even the first time she’s done something like this. She had a dog, one of the sweetest I’ve met. You could tell she came from a neglectful home but it didn’t phase her. She loved everyone. She kept bringing her back to that miserable place every time she got tired of her. You know why my sister finally got rid of her? She moved out with her boyfriend and the boyfriend paid more attention to the dog. She has done this before too. When she lived with her now ex wife they would pick up strays and abandon them when they didn’t have the personality they wanted. She even told me how her wife killed one of the strays because it killed a kitten they got. What did she expect? You can’t just put two cats together and think they’ll automatically get along. She talked about the wife killing the cat as if it was the most normal thing in the world.She no longer considers me her sister after my boyfriend heard the conversation about her abandoning the cat (we were Skyping when she came into my room to tell me, we live with our parent) and called her a bitch. She’s mad because I let him. I agreed with him. Now we’re both the trashy ones, and I’m choosing water over blood and she can’t wait until she can hit me. The hypocrite she is. She didn’t say anything when her wife stole from me and threaten me. All of that is justified in her perspective. I don’t even care. I just want to know where she left my baby so I can bring her back. She doesn’t deserve that. But according to my sister abandoning her was better than what she wanted to do when she got out, beat her.I know she’ll continue this cycle. She tosses people and animals like trash when things don’t go her way. The kicker is she wants kids. The kids won’t be whatever cookie cutter image she has in her head like none of her pets were. Will she toss them too when they don’t like her enough? When whoever she tricks into having kids with her pays more attention to them?I hope the cat is okay. Anything could happen to her. She’s so small and delicate. I miss her. I just want her to be safe via /r/TrueOffMyChest https://ift.tt/3krTss0
