Does a man who likes a young woman and the young woman is not interested so he finds someone else is that how affairs start jumping from one young woman to the next?

Answer 1

This is not really how affairs start. An affair is when the person is committed to another, usually by marriage, and enters into another relationship at the same time. A young man whose eye is on a woman who is already committed or who is not interested has no real choice except to move on. He never had a relationship with that woman, and so it is not an affair in any sense of the word.
