I have a question, ok this is going to be long so please bear with me because I need to know if I'm over reacting.

To start, I have a daughter whose now 24, I never had a problem with her going through teen years, I trusted her 100% she talked to me about anything she wanted, always asked before she did something, told me where she was and with who, I allowed her to start and go clubbing at 15 and never had any concern about it. Now my son is about to turn 15 and I can't trust him, he never speaks to me about anything, never asks and does what he wants (his father and I have split up) his father allows him to do what he wants so he hates staying with me because I have rules and boundaries, he's becoming someone I don't like.

Now for the question, he's told me it's typical teenage behaviour to ignore me for sometimes weeks at a time, to start skipping school days so he can go do activities with the army cadets (I found out he'd done this 3 weeks later, I didn't even know he was in cadets), to be in the parks doing God knows what at night with a 'friend' who I don't know because he refuses to tell me, he won't speak to me on the phone 'because I don't like using a phone' but whenever I see him it never leaves his hand, he's out with his friends 3 nights a week and every weekend he's not playing sports but if I ask him to spend 2 hours with me on a Sunday he's suddenly got something on so he's to busy to see me but my daughter checks his fb and he's sat bored waiting for his friends to go out. If he comes to my house I have to keep money locked away because he'll take it but this is all 'typical teenage behavior' is this true? Am I just over reacting?

I'm about to give up on him and I don't know what to do, any advice ladies? I'm desperate, thanks for reading.
