Conditional PR for sponsored spouses/common-law partners is very new. No one can tell you for sure how much CIC will "check up on" conditional permanent residents during their first two years here. Bottom line, no one here can tell you that it's okay to take the "break" you wish to take from your spouse. If your spouse reports the marriage breakdown to CIC, or if they decide to do a random check, you *may* be at risk of losing your PR status.
