First of all, realize that you've allowed yourself to fall in love with a woman who has no integrity. A woman who cheats on her husband is a woman that no man can ever fully trust.
Marriage is not about who did what. It is about who you think you can spend the rest of your life with. It is not the same as shopping for a car..where if one thinks this model of cars is cool then most likely you might find it cool too. You plan to spend your life with another human being, so my advise is not to generalise but find someone who you click with, it is not about where one comes from but rather about how you relate to that person. Best of luck!
