When a woman does thoughtful, personalized things for you without being asked, it means you're on her mind. People have limited mental bandwidth, so the effort she puts in signals you matter to her.
But if she is someone who goes out of her way to do nice things for you and she doesn't have to do that, that's huge. As humans, we're all busy and our minds can only hold so much information. So the fact that you're important enough that you get that kind of attention from her says a lot. In addition to that, when someone is personalizing the nice things they do for you to you specifically, this clearly shows that you're on her mind. She's put a lot of thought into this. Women are natural nurturers. We love to take care of the people who matter to us. So if she's going out of her way to do that for you, that says a lot.
