He doesnt want to go now.. im gutted lol but its because my 8 year old layla, has her friends staying over so the house is full of girls, so he doesnt want to come with me lol.
That what your son has said, is sort of a good thing. Because he does want to see you, and he is embarassed. Which i was when my mum found out.
May be.. this is just an opinion.. tell him you wont bring it up and not to be embarassed and if he needs help you will be there.
Im only saying this as i have kids and i couldnt bare not seeing them, and i know your the same, but he wont incase you mention the coke. But its best off leaving that maybe for now, just so you can see and speak to him..
Thats my opinion.. its entirely up to you what you do. Have a good weekend mate
