Spousal Support and Alimony: Lawsuit Settled Twice but Not Signed Still Ongoing Harassment

My question involves a marriage in the state of:Florida

Due to reduction in salary, my husband filed a motion to modify alimony paid to his ex-wife. Through mediation, the ex-wife agreed twice to a new agreement (the same agreement twice-with two different attorneys) After waiting weeks for her to sign, she then refused to sign both times without any reason why. This has been ongoing for three years. We had to submit thousand of copies of financials from our home and his business, only to turn around in a few months and update with thousands more documents. The ex-wife is now on her third attorney after having been fired by her former attorneys. Having endured the intense stress of this case for three years, we feel that the ex-wife is intentionally trying to inflict distress. I have endured anxiety and health problems due to that anxiety. My husband and I are deeply in debt, have zero savings, and absolutely no retirement....so the uncertainty of this matter has been extremely hard for us.
Can my husband or my husband and I sue for harassment or infliction of emotional distress? Thank you so much for your time!
