had to reply to this thread, never posted before.
Partner and I both played this game before first son, there is no method of cutting down playing time with WoW, the game is designed to keep you playing non-stop, many hours a day.
Your partner needs to quit this game pronto, just google wow addiction, there are millions stuck in a rut with it.
You are a single mum when this happens, you are better off as a single mum, WoW is not a symptom it is the cause of the problem.
I quit the game after ds1 was born, DP didn't, and continued to play for around 60 hours a week.
Eventually I Gave DP the big ultimatum, quit or get out of my life, he stayed and quit WoW entirely, and surprise surprise his business is doing really well again, he has set up an online shop to make extra cash, spends lots of time with the kids and is caring and thoughtful again. Obviously he did not really need 60 hours of 'relaxing time' at all.
WoW is the biggest waste of time, and yes I know people personally who have met and had affairs with other people they have got to know through WoW.
DP missed out on the first 6 months of DS1's life because of it, and nearly lost his business and family.
