My 18 year old son is so suppose to graduate this year but he skips classes all the time. His father and I have been divorced for the past 11 years, we have joint custody and we are trying to do what's best for him and our daughter. He stopped going by his father a few weeks ago and he refuses to stay home at night and he has a I don't care attitude. I have tried many things, he just argues with me or lies .I can't hold his hand anymore but I want to see him succed in life I love him but I don't know what else to do.Can anyone help me?

It is obvious he is not going to graduate if he is skipping class and not even coming home at night.

At 18 it is most likely there is nothing you can do legally to force him to come home or even go to school. But you may talk to the local resourse officer ( school police officer) to see if they know of anything.

One if you are paying anything for him, cell phone, call, and so on, stop, cut off phone, take car back and don't let him have it.

Tough love - you either put up with him as he is (and the way he treats you) OR you take a stand and tell him he needs to get out, find a job or go to school, support himself.

No middle road.

I agree with Chuck but you may also consider taking away other privalages if you can. Like Chuck said you can take away his phone but there is also video games, computer, car and money that can be taken away.I know that he is 18 but if he lives with you he should follow your rules and respect you or maybe he should be out on his oun so that he can realize that it's not as easy as he thinks.

Give him those tough choices now... school or full time work and pay his way. At some point, he will see the error of his judgement. He may have to complete his GED at a later time, but it will be on his terms. Sometimes they have to learn it for themselves. Hard for parents, because you know the challenges he can face, but that is part of growing up. You don't have to be harsh, but don't take the disrespect either. If he wants to be treated as an adult, he has to act like one.
Discuss it with his father, then have a family meeting to discuss it with him.
