I hope that someone can give me advice about my 18 year old difficult child. He is a senior in an alternative HS, and my husband and I told him yesterday that he could not live with us anymore. We have told difficult child that he could live at our house as long as he followed our rules, and he constantly lies and does whatever he wants. He has stolen my credit card several times and charged hundreds of $ at a head shop. He was truant from school yesterday, and today he was suspended from school because they found "legal" weed in his backpack. He is very good at manipulating other adults, and he makes promises to change but it never happens for more than a few days. He hangs with loser friends who have no interested besides smoking weed and chilling. husband and I have told difficult child that he could not smoke hookah in our house, but he does it anyway. He talks to a psychologist every week, but it does not really help. He was diagnosed with very slow processing speed, and is taking abilify to help with moods. difficult child is staying with his girlfriends family for the next three days, and then they will bring him back home. husband and I do not want him to stay at our house if he is going to continue to lie, steal, and get high. I feel like he will have to learn to follow the law and other rules the hard way, by not living at our house. But I really don't want him living on the street either. Do you think that we should be firm and not allow difficult child to live at our house anymore? Or should we give him one more chance to change? He keeps promising to change and he is begging to stay at home. But we have been lied to so often that we don't believe anything that he says anymore, and husband and I are really sick of the constant trouble with our son. I would appreciate any advice from others on this board with more experience.
