The question of moving out and what affect it has on your chances of reconciliation has a lot to do with the circumstances of the disconnect.
If your constantly at each other's throat or she's always stressed around you, it's not conducive to reconciliation. Sometimes you have to take a step back. Your not going to win her back by getting on her nerves and her behavior may even dampen your desire to reconcile.
It really depends on your situation in my opinion. Some on here live with their S, but are sleeping in different rooms/beds. Loosing that physical connection isn't necessarily a reason to split if everything else is amicable. But even under these circumstances you both will need to be willing to see professional help to resolve your impasse. Otherwise, the tension will continue to build until you have no choice but to separate.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
