I kinda disagree.

I'm kinda into DOTA too alot. But I always make time for my GF.
Example, every Wednesday (never miss) I'd go cinema with my gf after work.
During weekends, we'd plan something else like going jogging at park, go dim sum, etc.
Other example, we'd plan for future vacation. Example, plan 2-3 months on a trip. We look info & talk about interesting places to go. But some time, I also like some time on my own to do things I like.

Please give him another chance & try to make some plans to get him away from the evil computer.
