He has been a total dick this year, and despite telling us it was all great, turns out he missed coursework and failed the end of year exams. He now does have a sob story about why, but tbh after all the lies this year (and tbh he has form for this at A level saying he was doing well/ getting coursework done when it wasn't true) I don't know what to believe in all honesty.
He has been working this summer, and actually doing really well at that, but it can't be permanent. And his (overseas) girlfriend is staying with us allegedly till the end of August.
I'm gutted, and tbh also embarrassed that he has lied about it and we swallowed it all, and now he's left back at home with nothing. And angry that he has pissed our money up the wall.
I want to go nuclear this evening and tell his gf to get packed and out of the house, but that probably isn't the best idea initially.
So, any advice? WWYD?
