My SIL is a terrible person and I really dislike her
My sister in law is a drunk, drug abuser and a liar. She's made a mess of her own life, but that isn't enough for her.
She gets pregnant by a man who was in his early 60's. Now, she has an 8 and 7 year old. She goes on drinking binges which leads to periods of disruption as she fights with her now 70 year old partner. They never marry because she got married at 19, didn't tell her family and never got divorced. This has left her unable to get medical insurance. He has to work as a golf caddie to support two kids. Except, he's completely overwhelmed and doesn't really know how to handle two little kids and a drunk partner. He never had kids and at 70 is trying to just get through the day.
Six months ago the her body started breaking down. She says she has pancreatic cancer and is getting radiation treatment three times a week. But, she really "loves her kids" and is worried about them. This leads to family members sending her money and trying to help her. I get her a chance to get treated at a great hospital for free by asking a personal favor of my company's CEO. She never contacts the hospital as she's too sick all the time.
This week the truth came out when my FIL showed up at her "radiation" appointment to check on her progress. No doctor with the name she gave and no appointment. He talks to the doctor at the clinic she goes to "Cancer? She doesn't have cancer. She has a liver condition caused by drinking and drug abuse."
She is intent to allow herself to die. Except she can't just destroy her own life. Her daughters are clearly emotionally troubled. They cry for the slightest reason, are both seriously underweight, and say they usually don't eat lunch, never have vegetables, and don't really have normal bedtimes. My SIL refuses all offers of AA and rehab but she "wants to be there for her kids."
When she got pregnant I told my wife we would one day be raising these kids. It looks like sadly I was right. These girls will need therapy and time to understand what normal life shoud be for a kid. I don't really look forward to having to take them in but better now when they have a chance ten when they are teens and beyond help.
