From what I have seen he seems no better than a good friend with benefits , she shows him occasional affection but more like a mother than lover, there is rarely a spontaneous kiss on the cheek or lips from either of them. Nothing really natural that you would expect from two people in love at their age with no children to disturb them.
But for some reason best known to themselves they suit each other and stay together and it seems to work well from their point of view, if not always from the viewers.
As for her collection of toys, perhaps it’s because with them she has total control of the whole situation, and suits him because it fills a void that he can’t for whatever reason.
Although he doesn’t absent the apartment enough from the viewers point of view he does though have an agreement with Leora to allow her certain freedoms within the apartment to carry out her commitments, albeit not always as good as it could be judging by some comments on here at times.
I have a pragmatic outlook towards things, they bored me for a while so I am now on a monthly membership which suits my lifestyle, I haven’t initiated it yet but will do again probably once she clears her next period, until we get bored again. Hehe.
