Great question...one of the issues in our marriage had been that I was pretty obsessed with martial arts. I practice 2-3 nights per week and sometimes weekends for an hour. I quit it when my W dropped the D bomb on me. I realized that it had been taking me away from my family, my W...I was not present and left her by herself a few nights per week. It caused me stress at work b/c I wanted to get things done so i could go practice not be with my family and W. So, I cannot go back to that.
Your kids are 10 and 7; any chance you could sign them up for some MA classes and do that with them? Some quality daddy/daughter and daddy/son time?
