I want playing some game in girl mode with GF.

I want to do it. But I never told my CDing to GF.

Tell your GF, FIRST.
Then let her process the news.
Then tell her you want to hang out as girls together (if she is still around, and OK with the whole thing).
Get snacks and beverages, get the game, and have fun!

Sometimes the GF will not want to play the game at all. If that is the case be prepared for DADT or confusion...gl girl :)

Tell your girlfriend and make it all sound interesting.
She may accept your interesting story.
