Bernie, life is too short to not be happy.  Kids are much aware of Mommie and Daddy problems from when I was a child.  I feel that it is best for you NOT to stay in a relationship that is no longer the way it was...the way you thought it would be. I too am in a situation but I do not have kids and believe it or not I am still here with him.  My reasoning is totally non-selfish.  He does not have any family that he cares about let alone liking or loving them.  I feel he will be at a loss without me.  I am much older than you and I have seen too many young people not taking bs from spouses.  They pack up and off they go.  I applaud them.  They are not subjecting their kids to mental stress and possibly trauma and the parent can think clearly without the pressures.  I say go for it! Being unhappy is truly not what life is about.  Brenda
