There is a couple we know quite well, well enough to call them our friends. Recently they have changed, both of them lost weight and she went totally overboard on new clothes, makeup and fake tan, I didn't really think much of the change as a lot of people feel the need to lose weight or to make themselves more attractive for various reasons - including getting older!!

However I have just found out he was having an affair with a younger friend of both of them, she didn't know who or what but obviously knew something was up and suddenly found out about it, now I can understand her need to make herself more attractive, she felt like she was losing her husband. What I can't understand though is why people are unfaithful. They are staying together at the moment and trying to work things out for their kids sake but I really feel for her and don't know what I can do to help, at the moment she doesn't talk about it so I act like everythings normal. What would you do to help or do I just mind my own business?
