my gf sometimes can be a lil negative but shes starting to come around.....for me i just need to stress the plessure i get from jiu jitsu and how much i care about it. It took a while but now shell even watch UFC fights with me. i dont know how long you have been with her and im sure it upsets you for her not to be supportive. For me im a little over 2 years with her so when it gets serious it all comes down to give and take...
