Well, yeah, ya do sound rather shallow, to be honest. You do realise that people don't stay looking the same for the rest of their lives. Are you going to expect your W to be slim and young looking when she's 60? C'mon, you must realise that one's love goes deeper than just being attracted to a certain way one's spouse looks at the time of marriage.
Okay, now that I have finished bashing you, I also think you need to go to counselling to help you find a way to communicate to your W how you are feeling. Maybe there are things about you that annoy her, and you could both work on it together? M is about more than being attracted to one another (although, it is very important) ... it's also about unconditional love, being supportive, honest with each other, trustworthy ... I think you get my drift. Sometimes, it takes time for the M to settle, to find other things about each other that makes you attractive and appealing, like being kind, a good parent, a good listener, caring, etc.
BTW, how old are you and your W? I hope you find a way to sort this out before it gets to a point of no return. Do something now ... don't wait until you end up having an affair or leaving when there's a baby in the family. Now is your chance to show what your true character is, and why your wife should continue loving you.
Just a thought, I guess. Good luck!
