I think it depends on the couple as a whole, their relationship together, and how they both feel. They need to dicuss their feeling and emotions and figure out if the love is still there and if the relationship is worth saving. The man needs to be able to try an attempt to earn his trust back, and if he will end the affair. That is, if it's still on-going. I think it all depends on the people themselves, and how they feel about it.Some woman will just write off their guy and say see-you-later!, and others may feel that their relationship has hit a barrier, but are they able to get past that blockage. I myself have never been in this situation, but I know many woman that have, and the best thing you can do is think can you deal with this, and move on? Is he willing to earn his trust? And most of all, is there still love in the air, or has the flame burnt out.
