Spouse Changed Work Life Insurance

Hi:

My spouse took my name off of his life insurance policy provided through his employment. He then put his married girlfriend on as a beneficiary. He did this without informing me first. He said he did this to prove his commitment to her. We have 2 children, one is still a minor. We are in the state of GA and his married girlfriend is in N.C.

Is this legal? Also, how would this affect an alienation of affection lawsuit should I decide to pursue it?

I also have many pictures of them together, as well as some printed dialog that is publicly available of their adventures together.

Thank you in advance for your response.

I cannot advise you on the law in GA.
