I have a friend…who has been married only for a short time who thinks her husband may be cheating on her…She always asks me what kinds of signs should she look for but I have never been in that situation…What can I tell her to look out for with her husband?

If someone is cheating on you and you have all the evidence from their smell, to their body language etc. plus the fact that you know the person so well you know they cheated.
Do you:
a) Confront them
b) Strategically get yourself together and leave without their knowledge.
c) Ignore the situation in hopes that it will change.
d) Other
