I hadn't realized that my comments had been requested.
If you two have talked about this on several occasions and he is still not getting a clue, then he may be denser than diamond regarding your feelings. However since the women he points out are of a certain type ("dolled up" in certain types of clothes) then prehaps he also misses when you used to dress and preen yourself this way before the reality of children and daycare set in. The fact that he still remembers and takes the time to compliment you is encouraging.
I also think that you also miss the days when you could be the one with your hair and nails done with clothes that didn't scream I have children. You incorrectly feel that these women are competition becuase of their situation they can afford these things, and this is certianly affecting your self esteeem. You need to do something to feel better about yourself. Might it be possible to find a little extra in the family budget for some pampering for you?
