... Am I wrong to feel this way ....
There is no wrong way to feel
... I've always had a problem with my weight ... my body looks awful, worse and worse after each surgery.
If you don't like the way you look, there are ways to improve it. However, nobody looks perfect. There is a balance between finding a way to "look the way that will make you happy" and finding a way "be happy the way that you look."
... Shouldn't he love me just the way I am?
Of course he loves you the way you are. Only a monster would stop loving a woman based on her looks. However, what you really want to know is not if he loves you, but rather if he is in love with you:
... Shouldn't he be in love with me just the way I am?
No. Of course not.
"love" + "desire" = "in love"
Where does desire come from?
In 99% of marriages, desire comes from a spouse as a "sex object". What does that mean?
Female "sex object" = youth, fitness, body curves, attractiveness, slim build, breast size, firmness of behind, etc.
Male "sex object" = resources, success, ambition, confidence, money, power, dominance, etc.
How does this help you?
First, try to see the problem for what it is. There is nothing wrong with you. There is also nothing wrong with your husband. There is something broken in the connection that binds the two of you together. It is usually very easy to fix.
Second, your husband loves you as much in a size 18 body as he does in a size 6. This is not about love. Neither is it about sex. It is about desire. Desire is a dimly lit abandoned parking lot that connects love and sex ... unfortunately, our culture is so afraid of admitting the importance of desire that most people pretend that it does not exist. You are not the only couple that have a problem with this. I have lost count of how many times I have advised desperate men on these boards to read "man up" books in order to act more dominant, masculine, and confident so as to re-ignite their wife's desire. You can blame the 200 years of Victorian neglect of a huge part of what makes us human. Desire is the bridge between love and sexuality. When we ignore it, it comes back and whacks us on the head.
