Me Too. Sorry, have no help to give
My wife also thinks it is immature to play video games.
Whenever she says that I get mad and tell her to get out of my fort.:)
Well you certainly aren't alone... while I play Pokemon games on the 3DS with her (I know, lol) my girlfriend does not play most of the other games like this with me, but who cares as long as you can put some time in now and then
