My sister had a guy who really, really liked her. However, she really, really disliked him for almost every reason in the book. He had red hair, freckles, a little chubby, and not her type at all. But there was something different about him. He didn't give up. Not once for three years did he quit asking her for a date every time he saw her. She embarrassed him, hurt him, did almost everything she could do to run him off. But he loved her so much, he didn't give up. Finally, after three years - to the amazement of all of our family, she agreed to date him. Shortly after, they were married, and have been happily married ever since. (Fifteen years now) They have a wonderful marriage, and they dote on each other, and laugh about the years she would have nothing to do with him!
For some women, they do like to be "chased" .... so if you find someone you really, really think you want to spend the rest of your life with, then give it your all... she may just be wanting to have fun with the chase - just like my sister did, I think.
