I agree...you gave it a good shot! It's not quitting if you let them go, it just acknowledging that they won't adapt regardless of what you do. It is in the best interest of all of you to let them go. They will drive you batty and you will grow to really dislike and resent them. Don't beat yourself up, you tried to bring some stability to their lives but it will never work if the Mom doesn't make any effort. You lasted a lot longer than I would have.
