So we have had a rough couple months with my 17 year old....With lying and a few other things....Ok so here is the story...He has been with the same girl since he was 14 and it has always been drama....They break up and get back together and her mom always seems to run the show....So anyway I guess her mom told her that if she continues to see my son they would take her car and that she should be going out with her friends etc...but the worse part is is that she is like a child (the mom) she goes around telling people that my son know that her daughter is dating other boys so my son has been angry and depressed for awhile now....We have tried to talk to him and help him and all he does is get angry with us and walks out. He tells us to leave him alone and to stop prying in his life. I have to watch my son getting skinny and always to the point of tears. So the problem is that since the mom doesn't want them together every chance she gets to sleep out of the house he than lies to us that he is sleeping at a friends house and so far he is never there!...That is the case today and I don't know what to do anymore...He told his dad last night that he asked me to spend the night at "Kyles" house and when my husband came to bed I told him that I hadn't spoken to my son....so this morning on my way to work I passed by "Kyles" house and his car is not there....In the past I would contact her (the girlfriends) mother and all it would do is make my son so angry because I got involved in his life and no matter how many times I try to explain to him that by lying to go see her when her parents find out it just makes them more angry and not want her to see him but he doesn't get it!....I don't know what to do right now (because of him seeming so depressed)....I don't know if I should call her mom???? I can wait till he gets home and try to talk to him but he just gets angry and yells and walks out...We have tried taking the car, grounding him etc but he will be 18 in 6 months and he is using it all the way....I want to help him but at the same time I am afraid if I get to involved I will lose him fully. He is a very very sensitive kid and in his eyes he is head over heals with this girl and all she does is play games with him....Her mom is just an evil woman and I hate even dealing with her....I know that this is prob a phase but I want to do the right thing for my son...Any advise would be appreciated!!!... Thanks in advance.
