Dss is 9. He spends 50% of his time with each parent, literally.
His mum is getting married in June, to a chap who seems ok, just met him in passing. Dss thinks he's ok, although prior to this chap moving in it was just dss and his mother and so she was rather dependant on him iygwim
We (myself, and my 3 pests ;)) moved in with his dad last Aug, although we'd been visiting at weekends for much longer.
Dss is now experiencing a lot of anger. At just about everything. I know boys have a testosterone surge at this age, but even so, this is disproportionate.
I suspect there is a degree of jealousy going on, probably most of it because my 3 are here full time and he's not. He is closer to dp, common hobbies etc, and a lot of the weekend is just dss and dp off footballing, because dss plays for a local team that dp coaches. Given this I suspect some of the problem is not that he's not getting enough dad time, just that he perceives the other 3 to be getting more because of the nights that he's not here.
It doesn't help that he'll be missing out on stuff that he would otherwise do with us at the beginning of the summer holidays because he's off with his mum to Spain, and while he'll have a ball there, his natural inclination is to brood over what he'll be missing out on.
I need ideas. How can I help him see that the glass is half full, not half empty?
