Personally, cheating lovers ranks right up there with molesting children. Well, actually, right below, but still waaaaay up there. I mean, I think the whole of Western culture views marriage as a the beginning of a monogamy. Like anyone one else, people will tend to get sexual urges about someone other than their partner. However, if a person is willing to get married, or even to be in a relationship, it means they're able to control those urges. If you can't control them, you don't belong in a relationship. A single's bar is probably more suitable.

I think you're mixing up monogamy with chastity. Marriage means you're satisfied with having only one lover for the rest of your life. Much deeper than that, you're swearing that for the remainder of your life that you will have only one partner, both sexual and emotional. If you choose to break that vow, then I think any divorce is legitimate.

Personally, if I were ever to be cheated on, there is no forgiveness. Also:

No, I think it happens simply because the person they cheated on them with provided them with something they needed that the husband/wife could not afford them at that time.
What you're saying that if a spouse is unable to satisfy the urges of their lover at that specific moment in time, that allows them to be unfaithful?

And:

I propose that instead of getting hurt and placing the blame on our partners we should look to ourselves and our own insecurities.
This is the reason why so many women are caught in abusive relationships. Every time they get beaten, they don't blame the actual dick who is beating them, but rather themselves. They look at themselves and wonder what they did to deserve this, and how they could change. If we allow such betrayal in marriage, then what's the point of getting married? We say those vows for a reason.
