Ive never been married, but some of my friends are and a couple are divorced. I think communication is one of the keys to making a marriage last. I talked to one friend's ex and she said he just quit listening to anything she had to say, and always wanted to talk about himself and what he wanted. It made her feel unloved. I think women are geared for two-way conversation and if they don't get it over a period of time, they give up.
