Very difficult to draw any lasting conclusions about the relationship of this pair from the visuals.
Without speaking their language, or understanding their culture, it's difficult for us to appraise them.
There are many moments when they seem affectionate towards one another (and their dog!) while she tends to cater to his needs, in terms of food, housework and physical satisfaction, within reason, while he does not reciprocate quite as effectively as she does to his needs, which is not unusual in many couples.
They seldom row, exactly, though there are a few occasional sulks from her (not that often though) while he can appear pathetic, at times, for following her from room to room, almost in the same way that their dog does!
The dog always follows her, not him. She leads both of them (and us) a merry chase!
Her speed in flitting from room to room, on a whim, makes it hard for us to keep up.
She's well within her rights to move around at will, maybe trying to get some space for herself and some 'me time' which he may be reluctant to give her.
Then again she may be dependent on him for many things that we don't know about.
He may have rescued her from a tyrant or a bully, for instance, in the past, but now she's facing the opposite problem of dealing with his insecurities and his dependency on her for his needs, rather than being a victim.
What I'm trying to say is that we can't judge this couple by our own standards of behaviour in a similar relationship.
She does seem to have the whip hand, so to speak, while he has to tread a difficult line.
No surprise, though, if he's jealous of her being the centre of attention and not him.
Every couple on this site has a different kind of relationship and that's part of the fascination.
So we should not be too quick to make assumptions.
So far they seem to be coping under the unnatural conditions of their virtual goldfish bowl. I know it wouldn't work for me, if I was there!
What do others think? Is he a total write off? Or just making the best of a difficult situation to get through some financial hard times? Is she doing the same? Or just loving the chance to be an exhibitionist?
