It is just so hard to know whether the reasons they give us are the real ones or if it is just what pops into their brains and sounds good at the time. I think there is just an "overall" unhappiness much of the time and if pressed for whys - they throw out specifics that really weren't the actual cause, just a needle in the haystack. As my mom said when I asked what was wrong with my aunt and uncle when they split up, she said "nothing and everything". so, I think you might take his revelations with a grain of salt. At this stage, he is grasping at straws and it will take some alone time for him to really come to grips with it all.
Did you get out this weekend? Did H have kids? My goal this week (or next weekend) is to go see a movie by myself. I do think it will be empowering. I am gonna catch "Love Actually".
