Want from each other? Maybe a little honesty? I think the whole thing is hopeless. For one thing, in youth people get married because they are in love (or lust) and they grow up and possibly apart from each other. The thing is: they have no baggage except each other.
The second time around the story is different. They both have baggage. The thing is: do you want this other person's baggage or are you better off without them? I also agree that men are generally not faithful and have a terrible DOUBLE standard with regard to fidelity. This cannot be tolerated by me. I would forgive a guy if I withheld sex for a long time and he had to find it elsewhere but most men don't need a reason to find it elsewhere. They are only too happy to sample the pickin's all around them.
I also feel that men are simply not in reality about themselves and how they look with regard to aging and overweight. I honestly think some of them have a magic mirror! While I do agree that nowadays men tend to be more interested in their appearance than in times past, they simply are deluded and think they should be forgiven for their physical "imperfections" and get indignant that some women are picky but yet they can be heard making awful remarks about some poor woman's appearance if she doesn't measure up to the perfect 10 ideal. Sad but true.
