Is Leaving the marital home REALLY so bad?

[4luv]

let me clarify...i was trying to point out that i am thinking about leaving so that the real reality of his decisions will be clear...basically, sometimes the person that wants the divorce because of feeling alot of pressure and believing that the marriage is the cause of all the pressure may need a wake up call. i left for a month before and my hubby's brother who is staying with us told me that hubby was miserable and checking my facebook page everyday, hubby called to talk to me everyday, and realized that i was gone yet he was still unhappy. it just feels like its sooo much tension and pressure in the house that maybe the whole situation and relaationship could use a break. in short, what if i became the WAS?
