Dammit sensei, always on the same thread I'm about to post on, lol. Yea, this a funny one, I had one of these GF's a few years ago and it's going to be the same across the board whether it's jiu-jitsu, football, poker, anything a guy wants to do to be in his own space and relax; there will be estrogen interference. Now, you have have the TALK with her and explain that this makes you happy and she should want to make you happy, so therefore she should support what you love so that you can love her just as much. Keep ur pimp hand half raised as you discuss this so she knows your serious. Also, this TALK seems to go beyond the relationship with you and your girl, seems like the married with children life is a huge life change you gotta be passionate about making. Being locked in the grid can be a bit of a hum drum existence (working long hours, trying to impress people you don't know, etc.), but when your in love and your kids are your motivation then I guess it's worth it. Anywho, this is all just opinions based on our experiences so keep a level head go with your gut.
