The question

Spouse & I walked away from our marriage twenty years ago. We never legally separated or divorced. Also we never came together again, nor cardnel knowledge "sex". Me husband recently got a bodily-injury case with an up coming settlement. My obvious question is; is she entitled to some settlement money? She never involved herself in adding in my recovery. Also she is currently living with another male who have she admitted sex with him in their bed. Is she entitled to some of my settlement?
