Re: Mentally Challenged 17 year old
If the youngest son is never going to graduate from Harvard Law School, that's ok. However, a very important goal in the education of mentally challenged children is basic self care skills, and it sounds like no one is pushing him in that area.
He is eligible for special education services until he reaches 21 or earns the equivalent of a HS diploma. Has he been in school at some point?
The middle son, yeah, Dad needs to stop fixing that car before the young man gets into a serious crash and badly injures or kills himself or someone else.
It's not something your BF probably wants to think about, but ask him, "What is going to happen to your sons when you can't care for them anymore? What if you got sick? What then?"
