Cemar, I don't advocate Divorce for the sake of Divorce, but I can say that I've seen plenty of families that "stayed together for the sake of the kids" that hurt the kids far more than a divorce would havek, simply because the pent up anger and resentment made for an extremely toxic situation, that was not going to improve any because neither parent was willing to do the work to improve the marriage. It is quite possible staying together is more harmful to the children than splitting. What I am saying, is don't stay just because of the children. It does nobody any good. Stay if you can commit to improving yourself and your marriage. Stay if you love your wife, if you have any hope for the situation improving, or for a dozen other reasons, but don't stay just for the children. Nobody wins (especially the children) if the ONLY reason you are staying is for them.
I think you know you are full of it regarding the LD woman being attracted to a man. There are many facets to attraction. It isn't all just sex. Not only that, but it is quite possible your W has no clue as to how unhappy you are, or of the pain you are in. They don't "know that they treat their men poorly". In fact, I'd bet many feel that their sex crazed husbands are treating them poorly making them submit to sex regardless of how they feel about it. Cemar, I've said this before: it is all about communication. I know my situation turned around drastically once MrsGGB understood my feelings and how I tied sex to love. Sure, it still isn't perfect, may never be. It is however no longer unsatisfactory. You need to talk intimately with your W. You know, until you can grow yourself to the point where you can accept that people are different, and try to put yourself in your W's mind by listening to her about her feelings, I don't think you are going to get anywhere. Then again, I'm sure this isn't news to you...many folks here have said the same thing to you.
