Friend is internet dating and has met a nice man- he divorced 15 years ago and has had 2 shorter relationships in between. He has told her that in his first marriage he had an affair and it was the worst mistake of his life. I'm going to be dating again soon and wasn't sure what to think of this- is it a case of leopard never changing his spots or can people genuinely make one infidelity mistake? I'm not sure how I will feel about this when it is my turn to date- what do you all think?
