Dp plays games.
In our early days he was a complete cunt idiot over them. He would come to my house in an evening, get a meal, a shag, then he would make excuses about having to go home (a large variety of excuses!) but all he was doing was making sure he was home in time for his WoW raid or whatever it is.
I soon got him out of that by saying I wasn't prepared to be in a relationship with a selfish twat like that. As I was a single parent at the time, he was my social life, and I resented feeling used for a couple of hours in the late evening, then dropped for a fucking game!
He still plays games, no idea what, but all I know is if I ask him for something he can drop the game where he is. I think he has chosen his games carefully. I'm fine with this. I make sure we get equal downtime (have 13 week old!) so I can MN, watch a programme, sit on my arse and scratch it, and he is in charge of the baby for that time. Then I take over.
It works for us. If he was playing something that wasn't dropped immediately when I asked, I'd be very fucked off. As I'm sure he would be if I did the same.
I've noticed the stupid headset and chatting absolute shit to his mates/random strangers has stopped since the arrival of the baby so he can't be completely unaware of his annoying habits!
