When women are in a relationship, I find they tend to dig in their heels when you ask them to change, and get stubborn. I believe it's all about give and take in a relationship, so if I change some behavior that she dislikes, I expect her to do likewise - but instead I get the "I am what I am, take it or leave it" attitude. Is it the way I'm approaching things that's wrong, or is this just something about women I need to get used to?
