Bit of a back story - me and my DS12 dad split last year. We co parent well and DS sees his dad nearly every day. From March this year until August son went through some challenging behaviour at school including lateness to lessons, hiding from staff and vaping on 3 occasions. I was in close contact with the school, consequences were out in place at home and I got him in to councilling. Since starting councilling he has changed completely back to his old self, had got back in to his clubs outside of school and I have had several phone calls since September from school saying what a massive difference there is in him and his effort/attitude in school. Not a single negative behaviour point so far this term.
Now on to my problem. I found 2 vapes under his bed tonight. I called him through and he swears to me they are not his but they are his best mates who put them there last Thursday so his mum doesn't find him with them. After talking for a while and laying out the consequences if he is lying he allowed his dad to drive him to best mates house and tell his mum. Best mate denies it and his mum believes him.
I'm of the opinion he wouldn't let his dad drive him there and tell his mates mum if it wasn't true. The 3 times I found them he admitted it to me and accepted the consequences. I can read him like a book and know when he is lying to me and this time just feels different. He didnt shout, didn't cry, didn't get defensive just matter of factly said they were said mates.
What do I do? He has worked so hard to turn things around, is really focused on the particular sport he plays and fully knows the consequences vaping will have on his place on the team. All of this and how much he has engaged with the councillor makes me want to believe him but is he just pulling the wool over my eyes?
