Laura, 43, from So Cali, asks: My 23 year old daughter recently came to me in tears saying that after she and her boyfriend were together for awhile, that he cheated on her. This is the 2nd guy and she is blaming herself. What do I say to her? She and this guy were already broken up when she found out. She is really hurting, and I just want to help if I can.

VictorM's advice: The most important thing about a relationship is not money, not compatibility, not even love; no, the most important thing is trust! Without trust you basically have lots of bad times.

Your daughter's tears are understandable. Not only for the betrayal, but because it makes it difficult for her to trust again. And without trust, well... lots of bad times.

Cheaters will cheat regardless of who their partner is. Cheaters have a greed that no one person, no matter who, can satisfy. So, there is nothing she could have done to prevent the cheating. No amount of makeup, no dressing differently, no being in better shape, no coloring her hair for him... nothing! Cheating is a reflection purely and squarely on the cheater, not the cheated.

Will she accept and understand that answer? Maybe someday but probably not now. If she doesn't, don't worry. Let her feel down, let her cry. These are the signs of a nice girl for if she took being betrayed so lightly she wouldn't value herself as much as she does (even if it feels like the opposite right now).

And if nothing else helps, take her to The Outback and order the Sydney Sinful Sundae with extra sauce and strawberries... mmmm that stuff is so good it makes all evil go away.
