The sure way for a woman to find out if a man really loves her

The sure way for a woman to find out if a man really loves her and is not just interested in sex is for her not to give in to sex until after marriage. This is the way that it was supposed to be right from the beginning. In my blog novel here, it is main theme and it is clear that the love between the main characters would never have happened had it not been for the fact that sex stayed out as they got to know each other better.
