Is Leaving the marital home REALLY so bad?

[4luv]

I believe that Puppy has posted before that one of the biggest mistakes when DBing is leaving the marital home or master bed. I want to know why this is sooo bad? In my situation, it seems as though my hubby is able to really think clearly and evaluate his actions when he doesn't have me around. when i am in the house we could avoid each other but it is a constant stress on him and all he can think is that i need to get rid of this pressure. so I am thinking that i should go stay with my parents for awhile (about 2 to 3 months). at least it would give him the space he needs to sort out his true feelings. Any thoughts...(especially Puppy)
