Well, one other thing to consider, is that the things that would drive Keiichi and Belldandy apart are NOT things under the control of the Yggdrasil system once it has been restored.
Option 1:
Yggdrasil's Ultimate Force is able to keep things under it's direct control [AKA, Mortal Obstacles] but obstacles being put up by.. ya'know.. other Goddesses... the CEO of Hell... ect. are WELL beyond what that system was intended to work on.
Option 2:
Perhaps between the sheer will the Ultimate Force system was having to put into place due to the attraction power of Belldandy's Charisma to keep the two togeter, Heaven had to make their relationship an exception to the Ultimate Force system too keep it stable, feeling that with the three Goddesses of Time around him, they would do a much better job of handling the situation * snicker *
Option 3:
They don't need the Ultimate Force system anymore. In the beginning, Bell and Kei's relationship was on shaky ground on both ends. After the Ultimate Force was brought back online, that situation had dramatically changed. Keiichi has his full trust in Belldandy, and loves her to his core, as she does for him. Because of this, they don't NEED Ultimate Force to step in, because they will weather through it like any two people who truly love each other.
I personally think it's Option 3... but it's a few reasonable [IMHO] options.
