Your husband can sue you and your boyfriend depending on your states laws. Also, if your husband finds out you are dating, a judge can grant him a divorce on the grounds of adultery.
Divorce. You can't sue for infidelity. This probably won't work, but you could try getting a good lawyer and sue for "emotional damages," but why? Suing your spouse is only going to make them want to be with someone else even more. You need to work your marriage out face to face.
No adultery is not illegal in Louisiana. Adultery is not illegal in most states but it is considered immoral.
It depends on the local law. Rationally, Yes!
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.

No. The other person didn't commit adultery against you only your spouse did. Your spouse violated your marriage vows.
I see 21 states still have anti-adultery laws. What was the reason indiana legalized adultery in 1976?

Technically, yes. Practically speaking: waste of time and money.
In some states you can sue the ex-wifes lovers for adultery or alienation of affection. In many of those same states these are also criminal offenses, though rarely prosecuted today, even if the laws are still on the books. Traditionally you were not allowed to illegitimize your children born during a marriage, no matter what proof existed that another man was the father, but today you generally can prove in court that the child is not yours, and so you should not be responsible for its support.
