Is there any chance that Jenny and/or Submit are closet alcoholics or drug users? I ask because their relationship (or whatever it is) reminds me of Brigitte Nielsen and her fifth husband, Mattia Dessi.
Brigitte did some reality telly work in the mid-2000s (eg Surreal Life, Strange Love) where she began this weird friendship/fake romance with has-been rapper Flavor Flav. During this time it was obvious that she had serious mental and substance abuse problems (esp alcohol). And, in between her weirdness with Flav Flav, she was interacting with a young man, Mattia, who she referred to as her boyfriend. Mattia was about 20 years younger than her (and about half a foot shorter). His boyfriend duties seemed to consist of being almost like a manservant, errand-boy or nurse.... or ENABLER.
Like Submit, Mattia had no money, education, job or prospects and lacked any real talents or skills. And, it seemed that Mattia was just looking for an easy way to live a comfortable lifestyle (off of an "old lady") without having to actually work for it.
Anyhow, the messed up dynamics of both of these May-December relationships seem similar to me.
