Give him his time.

I'm sick of hearing about his mistakes.
I'm sick of him being the topic of every converstation.
I'm sick of you working so hard to bail him out.
I'm sick of you from keeping him from learning from his mistakes.
I'm sick of you not letting him grow up.
I'm sick of you bending backwards for him.
I'm sick that you put more energy in your relationship with him then the one with me, I'm right here. You regret losing him, yet I'm leaving in a year and I'm already drifting away from this house everyday.
I'm sick of you not noticing reality.
I'm sick of you being so native and childish. Don't you see that you are pushing him farther away everytime you coddle him? He doesn't want to be treated like a baby, he is 20. He wants to be treated like that man he wants to be. You're setting him up for failure, he things he is a 'man of the world' but you have sheltered him his whole way through life. He'll never be perared for anything.
You just need to B A C K O F F, and I'm sick of you not being able to see that.
I've tried to convince you to let him make his own decisions when you regretted all of the choices you presented to him. he doesn't want help. You don't listen. So now as you continue to fail to make a 'breakthough' and get more stressed out I'm tending to lose my patiences. I don't want you to hurt, but it seems impossible to walk on egg shells around you all the time, since now I'm hurting you by telling you the truth and you can't let anything go. Please, just stop. Everything will be fine, people need to learn from mistakes to stop making them, but that hasn't been able to happen for him because you don't allow any consquences for him. He needs time to figure one what's right for him, give him his time. And give me mine.
