Dear Robert Dean:
No, you cannot sue your spouse for alienation of affection. You can sue the third party lover for alienation of affection.
Stop condoning this behavior. If you make more money than your spouse and you continue to condone her behavior, you may end up paying her alimony. Do what is best for you right now, even if it is hard to do!
