The first time she request the young women to make a promise, it is a promise to not awaken love with feelings. Love is more than that. This time it don’t try to awaken love when the you think that you are a couple, you are in a relationship. Love is more than that. It involves a total commitment that lasts a lifetime.
Even when you make a commitment at a wedding ceremony, and sign a marriage license, if one or both of you are deceitful, it is just writing on a piece of paper. The wedding ceremony is just a party. The vows were just lines in a play.
Warning: some guys are warped enough that they function like this. They do or say what it takes to have sex with a girl. Then they dump her. She was easy. They repeat this process until they meet a girl who won’t have sex with them before she is married. They become obsessed with having sex with her and will even marry her to somehow ‘win’. Then they need a new conquest, a new challenge, someone new to have sex with.
