Enough - I'm sure that felt good, but remember in the future, the high road will leave you feeling better in the long run.

As for your H - you are young, you have no kids with this man, and he has cheated on you within the first year of your marriage. I'm willing to bet he was cheating on you with her BEFORE the wedding. It's odd, but I've seen it here several times - guys who are having an affair, but still go through with the wedding, because of all the momentum involved or whatever. If a guy is cheating in the first year of marriage, WHY DO YOU WANT TO SAVE THIS?

I'm all for fighting for marriages where there are kids, or 20 years of history. But a guy who has shown himself capable of this level of dishonesty, disrespect, and lack of character this early in the marriage? This isn't a midlife crisis, this is a deep character flaw. And it is not likely to change. Do you really want to have children with this man, and risk being a single mom in the future when he does this again?
