What is wrong with her?

She’s just a bitch.

She might jealous of you. :(
Talk to her and make it clear frm both the sides…

LOL. I agree with @Zachary_Mendes123…

I’d stop paying her rent, for starters…

When you say you pay her rent, you mean you rent from her and pay her for rent? Or you pay rent on her behalf?

I think she’s just a bitch. I’d avoid her.

It sounds like you live with her so avoidance doesn’t make sense. Why don’t you sit down with her and talk about how you feel? If she doesn’t respond, maybe you have to think of more separation.

Answer to an insult with an insult.

What? Some people won’t calm down until you show your teeth.

When she starts acting smartass again, just openly tell her to go fuck herself. Some people don’t even realise they’re asses until you point it out to them

I don’t think I can know from what you wrote. You’re her sister, so you seem like the best person to ask, but you seem to be looking to your thinking, which is confused. So try to clear out your thoughts and listen to your feelings. You may know in your gut what it is about.

The second-best person to ask is probably her. See if you can clear your thoughts, promise yourself not to react to her as best you can, and then ask and listen (not believe, but listen) to what she has to say, and the next thing and the next, acknowledge what she said so she knows you heard what she said (without agreeing or disagreeing) and then maybe ask some neutral questions about where that’s coming from. Sometimes you need to let people vomit up a bunch of upset nonsense before they get down to the source feelings.

She lives in LA for college and I live in Sacramento. So she would ask for money and I would help her when she needs it. But when she was making fun of me for working three job, I got mad and told her ” Bitch I pay for your rent” It also got me mad when she talks about my relationship so I told her “you have no right to say anything about us when you don’t know him or what we have been through” I just don’t know why she always try to put me down.

She sounds like a rude, mean person. If I were you, I would tell her that I don’t appreciate her meanness and I would also tell her that I was going to stop paying her rent.

I would also limit my contact with her.

Is it possible she genuinely doesn’t know that she’s hurting your feelings? Tell her. How she responds will tell you how close a relationship you’ll want with her. Sounds like you live in different cities; there’s no reason to keep in touch if you don’t like each other. But also, you’ll probably want to leave the door open to reconnect when she grows up a little.

What are your ages, and has she always been like this?

im 23 and she is 21. She just sometimes thinks that her life will be better than mine and would say things to bring me down. I don’t know if it’s jealousy or insecurity on her part but it’s irritating

I have a younger sister who is kind of like that. For one, she’s jealous of my position as the oldest in the family, although it’s been a royal pain in my tata neenees growing up.
All of her life she wanted to be the golden child, the favorite, the smartest, she wanted to be perfect. It just got all twisted up in her as she got older.

Quit paying her rent and giving her money, and back away from her for a while. Don’t cut her off, just be mildly unavailable. She needs to grow up. If she’s anything like my sister, she truly loves you and and wants you, but as long as she thinks she can walk all over you she’ll keep doing it. She needs a wake up call.
