I agree with Wolf.If you do end up splitting up because of this girl you will probably realise in a couple of months that you really did love your wife more than you thought and there maybe no way of fixing the situation. Its your choice mate. You could lose 10 years of marriage for a fling that might only end up being a one nyt thing. some people can have affairs all the time and hide it well without a conscience. i suggest if you are not one of them people then dont do what you wouldnt want done to yourself.If you are one of them people what she doesnt know wont hurt her. 🙂
