Jeff, this is not unlike my sitch w/ S18.
I'm no saint, I've had conversations with him that I now regret. There is a car, one my mom sold to me last December, that I basically used to bribe S18 with. I didn't work, but even if it had, I am sorry I tried. It wasn't fair. I learned my lesson. So, I dropped the rope with my own son. If he chooses to spend time with The Abuser, he is old enough to make that choice and live with the fallout.
Now, when we talk, I act 'as if' and he's really bewildered by that. (Who knew you could actually DB your own kids?)
love, Goldey
p.s. I think you should treat yourself to a movie or a video arcade or something tonight, Jeff. Invite a pal to shoot some pool, or whatever it is you guys do when you gather (I don't really need to know the details, really).
Peace.
