Hi sandra, it is very sad, but questions need answers, and I do believe it would be very hard to forgive if this happened, but your friend also has to ask herself, why did it happen? had she gone off of sex, had she let herself go, did he feel unloved, they need to talk and they need to be 100% honest with each other, the truth hurts sometimes, but truth is better than lies, if they are going to survive, they really do need to ask each other some serious questions and to respect each others answers, you must not just tell her what she wants to hear, what good is that? sit down with her and ask if she really wants your opinion, and if she does fine, but never encourage her to ditch him, that must be her decision, if indeed that is the path she chooses, I hope they can sort it out, but there will be a lot of tears on both sides before it is. wish her good luck, Ray xx
