Parties with unstable behaviour

Yesterday I was meditating a couple going through a divorce. I sensed something was not quite right when one party started the dialogue and continued to talk without giving anyone else a chance to speak. This person displayed various behaviour during our conversation. There were times where the person broke down, sometimes rude, sometimes blaming others, etc. This person conversed on a variety of topics which, most was not about the subject matter in hand. Whenever we get into the case of the divorce, it was avoided by self-pity statements and never getting a straight answer. This person also shared that he is undergoing treatment at IMH and is under medication.

I am curious to know what you would do? I shall be grateful if you can share your experience and thoughts
