I second that, and add that the boards have helped some people, me included, grow. Grow more mature emotionally, to be specific.
My earliest posts focused on my wife's radical feminism and how it was affecting our relationship. I was totally focused on how she was the root cause of my pain. I've come a long way since then (although I still think that her feminism has nothing but a negative effect on our relationship, it's but one of the cogs in the big wheel.)
Look at it this way: If you do split with Mr.Hap, and if you do intend to get into another committed relationship at some point, don't you think you'll be better at picking a suitable partner?
