Christ the first minute of that video is depressing and I can't watch the rest.
Basically the original wedding Photos were taken at Alison's folks place. For whatever reason they rushed to tie the knot in almost months after meeting but apparently Jake's family didn't know about this nuptial event. So they get to find out by Youtube video!
Not only that, but just for good measure, their newly-revealed daughter-in-law continues on discussing they need household appliances and please give generously. That just seems shitty, you lock Jakes family out from making one of the biggest decisions of his life or even being aware of what their boy is up to, but you ask them to help set you up too.
It's like from the get go she went to some length to cut him off from his old supports. Cuck or not that's pretty sad, he probably thinks he can't turn to family after going this far, and probably ended up cutting his friends away because they were not the "right sort of friends" in his missus's eyes.
The body language is...it's not that of a couple, they don't know how to cuddle up together, they can't even kiss for camera. She looks bored till the point where she can beg for free stuff. Jake has more of a physical relationship with his cat!
If your newly married and all, and considering they rushed while in a time-frame which wouldn't of allowed for that "new relationship smell" to wear off. I'ld expect more cuddling and general...joy?
