A girl called me a scum and said that every time I slept with a girl, I broke up. I said, what do you want? Why only blame me for their indiscretion before marriage?

So you are really scum. You are right. It is true that a girl sleeps with you before marriage, but you should know that the main reason why a girl sleeps with you is that she likes you and wants to stay with you for a long time. It is best to get married. Girls are carried away by love. Desperate for love, you break up after sleeping with them, which shows that you have no plans to marry them for a long time, just playing among girls, so girls are right to say that you are scum.
