My mum has given my sister somewhere between £50k and £100k over the past 10-15 years as she is completely unable to manage her finances. She has a nearly two year old ds and lives with his dad. They took out a mortgage based on their incomes a couple of years ago but obviously didn't allow for all their outgoings as they are consistently broke to the point where my mum has had to take out an interest in their house. My sister was on the phone, again, to my mum at the weekened telling her she can't afford to run her car and is now looking for a cheaper one but told me two days previously that she has booked a cheap holiday abroad with her friends. I had no idea my mum didn't know and mentioned it today. She looked crestfallen. I don't think she knows what to do. I don't tend to get involved but my sister is 32, intelligent and I think should have sorted her life out by now. I keep telling my mum to stop giving her money. I love her, she's my sister, but longterm it isn't sorting her problems out. Just interested to see what you all think.
