is it all the same??

So why is it when you are comfy in a relationship it seems all the things that used to make you feel warm and fuzzy go away? Or do they and you just notice them less and less??? I used to think I was a good catch in many different aspects but lately I don't feel that way...I almost feel like a ball and chain...like put a fork in me cuz I'm done...sooooo not right and not good for the self-esteem. I am a very fit, big breasted(natural) blonde chic that's super cool! But yet I feel I'm everything but what my guy is looking for...and that's the last thing I want. I get compliments everyday from random strangers but its the LAST thing I want! I want the man who is supposed to spend the day and night with me to be the one feeling he is satisfied and lucky to be with me a woman of my demeanor...what I represent and how I look and feel about everything. I guess my question or wonder is, how do you get that back? How do you not NAG at your man to make you feel good and do you not make yourself feel that way w/out your man? I want to be that hot woman my man tries to look at on a daily basis for wants and desires whether it be to fantasize about or that girlfriend that is always there for you....help!!!!!
