Lemme guess, they're splitting them up so they can try and rekindle on the will they/won't except this time it's will they/won't they get back together? So they can keep the old sexual tension going again, because jeez, having people in an actual relationship is just boring.

I just don't really see the point of this. They spun out the relationship for so long and it was such an integral part of the show, that breaking them up now seems pointless and counter-productive. Except as a lazy storyline gimmick. Which I'm sure it is.
