I will give you and hopefully others some words of wisdom.
Anything can become a addiction.ANYTHING.
Food,drugs,alcohol,sex,video games,computers,online forums.....I could write examples all day.
Its how we cope with these addictions that heals us.
I am addicted to food,porn,sex,WOW.....but I do not,would not ever pick Porn or WOW/any Game for Sex with my Lady/wife.
I would literally walk on broken glass and cut my own flesh before I would choose anything like that over her.
Now I admit,I have taken a early break with her because I needed a bite to eat. LOL...But I do not make it a habit.
PS- There is a site called http://www.gamingsucks.com/
There is a term for this problem,its called "WOWWidow"
Also in perspective now I think about it,I am also addicted to my Wife.I guess if I must be addicted to something,this is the best one to be addicted to.
