I hope that by reading what you have written, you will realize that nothing changes if nothing changes. I agree with Anvil...you ARE much stronger than you give yourself credit for, and you HAVE done an awesome job with Andrew. Don't let D drag you back into his chaotic life.
I'm sure you can figure out a way to make it where it's not so comfortable for him to stay there...whether it's sarcasm (okay, so I LIKE sarcasm), being a b**ch, or just telling him he needs to go. Yes, I know it will hurt Andrew, but he's got a terrific mom and he will be okay...D is going to leave anyway...we know this. Heck, I think even Andrew knows it.
You know what to do...hugs and prayers that you can do it.
