You are right to be worried about your son's behavior.  I wouldn't assume quite yet that he is going down the same road as his father did, but with that background it's great that you are trying to stop some of his behaviors now before things do get out of your control.  

First, it would be helpful to know what types of discipline you have tried already.  What did you do when you found out he forged your signature at school, or when he ditched school to hang out with a girl?  It's difficult to know specifically what advice to give you until we know what you have tried and what hasn't worked. However, for starters, make sure that in whatever type of discipline you use be sure that you are being consistent.   Make sure that the punishment fits the crime, and make the discipline immediate.  Teens respond better when they have negative consequences immediately rather than saying for example, "next weekend you're grounded."  

If everyday consequences such as taking away objects or priviledges continues to be ineffective, and he continues to do things like run away, sneak out, or break the law, you may have to go to the next step which is getting police involved, or getting him involved with the dept. of social services.  

I know going through teen issues can be very disheartening.  Sometimes it helps to talk to someone.  The good news is that there are many resources out there to help you.  If you would like any further information, or just need to talk to someone, please feel free to call our parenting hotline at 1-800-448-3000. We're here 24/7 and it's free to call.

Remember to take care of yourself right now.  With all this stress you need to make sure you are talking to friends/family  and even your son's school counselor about this situation.  

Take Care!!
