No, he is not cheating on his wife.
Yes, its called sue for divorce!
Sue for divorce, yes. Sue the other party for alienation of affection.
A cheating wife is not necessarily an unfit mother, unless she is not looking after the children properly and that fact isn't only the purview of a cheating wife.
I live in California and I never heard some cases about a spouse suing the spouse because of affair or cheating. The only way a spouse might get in trouble is when and if his having an affair and not supporting his children under age. But for a wife getting in trouble because of her cheating, it will be hard.
You can sue your wife for divorce, but I believe you can sue her 'partner' for 'Alienation of Affection'. Contact a lawyer. If you can prove that she left you for this 'partner' you might be successful.

A husband cannot sue his wife for embezzlement of their joint property. He also can't sue her if she embezzled from someone else.
