If you have already received absolute divorce then equitable distribution is not viable. Unless there was something stated that ED would be decided at a later date…neither of you can go back and get anything that was marital.
Check your papers. A settlement, even if you can’t afford an attorney, would be that you are entitled to 1/2 the marital assets at the time of separation. Which includes bank accounts, retirement accounts, savings, furniture, vehicles, homes. This would also mean that you would need to go back to the date of separation, and see if you are also entitled to alimony. If he makes more than you, you can request alimony as long as you did not sign away your right. If your divorce does not say anything about ED being decided later, then you don’t owe him anything and he can’t get it, nor can you get anything from him. You are divorced. What you took with you or have acquired since separating is yours and the same is true for him. If the home was his prior you may still have a vested interest but the attorney would need to answer that.
A lawsuit against her for Alienation of Affection would be time consuming and expensive. You would have to hire an attorney, prove that you had a viable marriage and that her actions intentionally alienated his affection from you. It’s difficult to prove and often just not worth it. I understand your frustration over this but keep in mind that everything comes back around. More than likely he will not be faithful to her either…IMHO, you can’t take someone away from someone else and expect them to be faithful to you.
