Are you going to demand that she wear heels during the week lest she look shlumpy?
Were you unattracted to her overall or only from the ankles down?
This topic is as silly as it sounds. Frankly, if her whole appearance changed because of a pair of heels, I think she deserves better, and you, well……
I understand that heels can dress up a look. I understand that you are tall and feel more comfortable with a taller girl and came with a certain expectation of her.
Your entitled to have your preferences, but you’re faulting her for not guessing what they are. That’s a very big problem in marriage, when people expect their spouses to guess and know what their needs are. You need to start relationships in the right way. Take responsibility for conveying your needs and preferences, and don’t get mad at another for not being a good navi.
I think you should ask the shadchan to ask her if she would mind wearing heels on the next date. See if the attraction changes, and then start working on yourself to stop measuring attraction with a ruler.
