Re: Unsupportive spouse
I agree wholeheartedly with Lynn Seiser. In my opinion, being married means that you have committed to always place your family's interests above your own interests.
It may be that your aikido training is in your family's best interests--or it may not. Only the two of you can decide this, and only if the two of you talk about it openly and honestly, without preconceptions or a desire to win an argument.
Consider this another application of your training. The challenge before you is this: can you find a way to resolve this conflict positively for all involved?
