I find this interview with Mary, RZ's sister to be very sad...and also very revealing. Mary was RZ's confidant and it appears she believed that RZ had a great deal of difficulty in that blended family. JS allowed his two older kids to be "openly rude" to her. This hurt RZ so much that she told Mary that "by the end of summer" she might have to tell JS she needed "time to herself."
Also the subject of marriage appeared to be off the table.."not being discussed at this point."
So RZ's only problem was not DS. She and JS were not this divinely happy couple to be envied.
RZ had just spent...was it two weeks...with those older disrespectful children who Mary says "did not want her." This must have been very stressful. Not to mention that DS seems to have had a good relationship with those older kids...she calls them Maxie's "brother and sister" on the Foundation website and speaks of his happiness at being at the same school they attended.
So RZ was the odd man out. I wonder if Max was starting to emulate the disrespect that the older kids were allowed to get away with by Jonah? The situation may have been very tense in that house the morning those older children left.
In any event, it seems this was no great love story. Whatever the arrangement was, it was unraveling, at least this is what RZ confided to her sister. It certainly points to unhappiness and stress...a component that when combined with the horror of Max 's death, could easily explain the suicide.
