I am 26 years old and I date a 27-year-old guy, who is also my fiancé. We have been together for four years but recently, I was told that he was having an affair with a 16-year-old girl. When I confronted him, he confessed and asked for forgiveness. I was angry, not because he was dating her but because she is a minor. I feel cheated and betrayed. Already, we are planning to have the family introduction and I don’t want it cancelled. He has told everybody that he would not cheat on me after we are married. But my friends are of the opinion that what happens in courtship can happen in marriage. Is it possible for him to change? I am confused because our parents are waiting for us to pick a date for the introduction.
