What Would You Do?

Scenario: You've been in a relationship married for seven years. Your spouse? Extremely rich and works for one of the biggest corporations in the country. You live in a nice ass home in a rich town & have a kid or two. Everything is going great until you find out that your spouse is cheating on you, occasionally, that is. You've found out that your spouse has been cheating on you during his/her once-every-couple-of-months "business" trips, always with the same person too. What do you do? Do you break up/divorce the person? Do you ignore it? Do you try and make things work? Note that you're pretty much all out on your own, away from family & friends and that your spouse is extremely wealthy and the one maintaining you. Are there certain circumstances/measures in which you would allow cheating? Or is cheating always ground for a divorce/breakup. And for those who say "it depends," what exactly does that mean?

Chime in.
