Being used for money

For context, i work in singapore and earn 20k+ ringgit per month, and would go back to KL almost every weekend. I noticed every time i go out to eat with family none of my siblings would ever offer to pay first and i am always the one who ends up paying. I know they’re gonna pay me back but if it’s with my parents & little sister who is a still a student, of course i would not ask them to pay back. And the rest of my siblings never pay back on time. I mean it’s not like i need the money, but it’s just common courtesy. Doesn’t mean i don’t need the money they can delay paying me back. Other than that, one of my siblings always steals my stuff which i leave in KL and she almost never asks for my permission. She thinks because i’m in singapore, she is entitled to use my stuff. And she always expects me to bring home food whenever i go out and when i do, she never offers to pay. Don’t get me wrong, i like sharing rezeki and i’m not the type yang berkira but i feel like sikit2 is ok, too much is not. Other than my family, one of my friends also does this. Every time we hang out i’m always the one who pays and if i don’t remind her, she will not pay me back. I mean if it’s just roti canai i tak la kedekut nak mintak balik, but idk, it’s common sense to pay someone back yang tolong bayarkan dulu kan?? Ke i yang petty? Also she previously owed me money against my will as in we went out to eat something super expensive and when i asked her to pay me back she said she didn’t have the money and proceeded to pay in instalment. And guess what, she still owes me about 150 ringgit and supposed to pay it off in june but until now no news. Afterwards selalu jugak hang out tapi dia takda ingat nak bayar langsung lmao. I let it slide je la sebab nak halalkan but i can’t help but feel like getting used for money? Idk if i’m petty. Anyways, just ranting.
