Without going into details, but I met through an organization a lot of women trying to recover from cheating husbands. Most women forgave their husbands, some separated for a while and eventually went back together, even went back to abusive husbands. Most of them had children.
Some others had their own affairs as a result of been so neglected,.When that happened most husbands left immediately blaming them, although they had not been honest themselves to begin with.
Fewer just left them, no forgiveness at all.
Nevertheless, I think it has to do much more about personality and how do you see a relationship than if you are a man or a woman. Also the dynamics of each relationship is different and this has also an effect on the other person's reaction to infidelity. Other thing to consider is how the partner finds out: it was a honest conversation or by discovering the lie. This is an extremelly complex issue, which changes from one relationship to other. But in general women tend to be more forgiving
