Girlfriend, do not worry. You have to become a creature Unlike any other. You have to learn the Rules now. It's stupid, it's dumb, it even seems manipulative, but the Rules work so well, even the cat will love YOU more.
I know you need the Rules, because you are already defensive- nobody thinks you have cooties, but you are already thinking something MUST be wrong with you. You could go into a downward spiral from here, fall into depression, maybe evn get clingy! (the worst feeling on the planet is to act clingy to a man who is walking away saying "get off me") so pull yourself together, get to the bookstore and start on a personal enrichment program that will change your life ( and love life) forever- you are going to adjust the way you feel about yourself, your focus will change, and he will be beggng you for sex, not the other way around. It's not expensive either.
The catch is that you have to learn how to look at the long run. Just like keeping fit and staying healthy; when you look at the long run, you know what is best, and when you have to go without five cookies with coffee at 10am, and the little indulgences, like saying hello first, will seem just like a sickening donut-- you won't even want it anymore.
The book is called The Rules, but there is another one called, The Rules for Marriage, and one called All the Rules, whichi I think has all in one cover. Another great book is Passionate Marriage which talks about how to hold your own personality separate, not melted into the relationship. Once you learn to do this, there is sometimes a missing of not being, but just live- life is great!! you will love it again, but not while melted to anyone. just start reading
