A friend I know used to be married to a woman who has played him badly for years. They're supposedly got two kids togeher who don't bare any resemblance to him, but in spite of being cheated on and physically abused by her a couple of times that I know of, he'll drop everything if she shows any signs of interest in getting back together with him. He was actually dating a really nice woman a couple of years back when his ex got wind of it and deliberately threw spanners in the works.
In saying all of that this woman Josh got mixed up with seems to have similar traits, but to a higher level. Seems from that clip that she's a complete con artist that took things a bit too far in this case when she thought that Josh was going to be a great cash cow for years to come.
