Hi there. I'm at my wits end over this. My 18yr old son thinks he can do whatever he likes now that he is 18 including becoming totally inebriated and lying about where he is staying at night and not going into college. This is all bad enough but he seems to have no respect for my rules or my feelings and i have evidence that he is being egged on by my xh who seems to delight in his power to influence my son and undermine my position. My son stays with me about 2 thirds of the time. Can anyone offer any advice. I think this situation is going to be very difficult to change as my xh's hold on my son is very strong but if someone could offer some ideas on how to cope with it that would be great. Thank you
