I am not surprised to see that more women leave then men. I think women need to feel they have a purpose in a relationship meaning they need to know they are appreciated and loved.
My DH and I have talked about this at great lengths this past weekend. As a matter of fact, I almost left in the 4th year of marriage, mainly due to him always being at work, gone, never home, and I was alone a great deal. He became a stranger to me. Last year, around August 2003, 13 years of marriage, neither one of us were happy, he and I both felt neglected at some level. I tossed myself into other things to deal with his absence for years, college, separate friends, even separate vacations, and at that point in our marriage, both of us felt we only stayed for the kids, not each other. We kept putting everything on the back burner, neither of us wanting to make any life altering decisions, but last Christmas we decided to separate. We were fixing up the house, knowing that we were going to put it on the market in the summer of 2004. In May 2004, we decided to stay together and sell the house and move anyway. Relationships are hard, at some point, one or both are going to want out, it is a given, maybe it is the lack of communication, the absence, the not seeing things eye to eye, one feeling they don’t understand them or the other person, or just plain stubborn, who knows, but I honestly think women expect more and will walk away quicker when their expectations and needs are not met.
BTW, we both agreed we are glad we decided to stay. He is a rare bird and a good one.
