Strong disagree on people not changing, my partners brother was a heavy alcoholic at 30 and he’s now 5 years sober and has children and hasn’t touched a drop. He relapsed in his first week and nearly died.
People can change, they just have to want to. Of course this isn’t applicable to all but generalising your situation to everyone isn’t helpful to people in these positions.
On the flip side so show that I understand people not changing, her uncle has currently lost his family and maybe soon his job. Every time the kids are due to be with him he’s completely shitfaced and the adult dropping them off refuses to give them to him in that condition and that still isn’t enough for him to want to change. I bet he has seen his own children for over a year. He is constantly lying and we think he owes money to people because he’s usually in a bit of a roughed up state. It’s sad but until he wants it there’s nothing anyone can do.
Her brother is still a testament to the way people can better themselves though.
