Honestly, I think this is a really good thing. You might actually be scaring him a bit. Because if you're not going to get all worked up about his choices and his life, HE just might have to.
And I agree, alot CAN happen in just a year's time. I've seen it with my own difficult children. And I can recall most especially with Travis fearing that he'd never pass age 12 maturity wise.
I do think the "last" miles can be the worst. I know for me it's been rough. My biggest hang up is that I'm afraid I might not ever get the two difficult child's outta my house. (notice I'm not laughing) And this fear is STILL there with both of them doing so much better these days.
Has the Residential Treatment Center (RTC) spoken with you at all about what will happen once the magic birthday rolls around if thank you hasn't improved at all?
