I (m30) gave my sister (f28) £3000 to buy a house with her boyfriend and now my parents want me to pay for her wedding.

Im from the UK. My sister is 2 years younger than me and has always been spoilt by our parents. She was able to train as a midwife because my parents paid for her accommodation etc. Im not saying shes lazy but she definitely doesnt do anything she doesnt want to do. If shes told what to do at work shes very very vocal aboit it. Example, she was asked to stay at work a bit longer one day and she just said no and went home. She said people called her names because of it but she said she didnt care.<br><br><br>Im not sure why shes the way she is, maybe its because we have parents that cater to her every need. I will say this, i dont get treated any differently, my parents are lovely to me but they know i dont need any help from them unless its something small. But they know my sister is happy to recieve anything shes given.. so they probably cater to her because they want to look after their kids. But i think there is a fine line between looking after your kids and spoiling them.<br><br>Out of respect for my parents i will just call my sister "my sister". So my sister has now purchased a house with her boyfriend of 5 or 6 years. Tbh she didnt really do anything and just sat back and let her boyfriend do all the work (not much i can do). My parents gave her £10,000 and she asked me for £3000 which is fine, im happy to help my family members so i gave it to her and shes now got a house. By the way £13,000 was just for a deposit.<br><br><br>My parents rang me yesterday and asked me if i could spare some money towards my sisters wedding. I asked how much but they said they didnt know yet.. so i kind of nodded and said maybe.<br><br>I dont mind giving them money, im happy to look after my family but my issue is that it appears my sister seems to rely on getting her way with everything. I know shes an adult so thats not really my problem but what does bother me is that she seems to get everything she wants due to people giving her money. Like.. give her money so she can train for the job she wants, give her money so she can buy a house and now give her money so she can have the wedding she wants .. its just too much to continually give her everything like that and lets people get away with doing whatever tf they want.. I will admit that this point sounds a bit weird but any way.<br><br>I also dont have much savings.. probably around £5000 myself and about £2000 in a different account which is currently being spent on home improvements. I dont have any other immediate family.. no other siblings, wife, kids, etc. So i do have some money to spare but im not made of money and i give everyone around me money once in awhile and im getting a bit broke to be honest.<br><br>What i am thinking of saying to my parents is "i will give your money if you ask my sister to pay for the wedding herself. Make sure it isnt getting paid for by anyone else. She can live within her means".<br><br>Info: will this be rude? Should i just give them the money?.. it will be split between 3 people, my sister boyfriend and my parents. They are fairly well off tbh and so am i so it will be no hardship to them but i can see my sister struggling.
