Ask your c6 eat banana, he is much wrost then his young brother, his young bro paid his own money but your c6 pay her mom with you and your mother money. He only concern your $$$ not you! Ask him to give up his business or earn $$$ and pay himself then everyone will shut up, otherwise, he shutup and do what you guy said. You got "no say" to how you use your $$$.
To be honest, you are too stupid and you should stop him in 1st day. I do appreciate your 99 to reject paying back the loan shark in 1st day that stop "big bro" to gamble again! So what you should do? Stop paying even you got $$$. This is the only way to rectify this wrost situation.
I am paying my mom and dad few thousands each each month, and paying all their billed expenses. Few year back, I got laid off, then I immediately told them I have to stop this as I don't have income and only can continue after I have a new job. They totally understand. Lucky me, this was only last for few months.
Lucky you, you are in the right track now. Keep up with this and don't even pay a single dollar to your 6299. This is to help you, your family and your 6299 family. This is you, your c6 and young bro create this disaster!
Yes, with this list your C6 will know exactly how much his parents need per month. Giving the 2 of them 20k per month is outrageous! The list will help him to wake up and clear his brain! Might as well you list out how much you 2 a spending for comparison...Normal life vs luxurious life!
What you have said to him was totally logical and rational. Don't blame it on yourself. It is time your C6 wakes up from his 孝子夢!
