What I am about to type is really from the mentality of the West as far as I can see it, I cannot comment on the Philippines as I am a Brit.

Personally, I don't think there is any difference in the perception of adultery in the UK between the failings of either a man or a woman.
I feel that men feel the same pain as women contrary to popular belief.
The feelings of desolation are as equally severe for both sexes if love is shattered by a "mistake".
Both sexes are just as much to blame and both need to fix it if that is what is decided.

Women do not have a monopoly on emotions, it is just that these emotions come out in different ways.

For me it is very simple: If you love someone you cannot cheat, as love is too precious to break.

I hope this doesn't sound too simplistic.
