I know. He is mr overreaction, he isn't happy so he jumps ship, he goes to his mums n realises he's miserable so he wants to come home. I've told him to think about it long and hard for a good few days and come talk to me like a grownup.
I'm coping because I don't think he actually means to fuck me about. I think he's just completely fucked up by his own less than ideal childhood that he's never ever dealt with. (I know this makes me sound a mug but I'm really not excusing him, he's been a twat too).
His weekends up to the age of 11 were spent sat on the pavement outside the pub while his dad got wankered all weekend. After 11 he was free to fend for himself. I think the fact that you're supposed to spend a lot of time as a family and how hard family life actually is (when done right) has come as a massive shock.
We'll see what happens, he's at his mums anyway, I asked him to go at about 4ish (he'd been here from 2) as it's bloody exhausting trying to be neutral. I spent half my time wanting to beg him to come home and half my time wanting to boot him in the knob
