Sex File: My wife wants a break from lovemaking — can this end well?

It's not easy when one partner stops wanting sex. The partner whose bids for sexual connection are constantly rejected can't help but feel unwanted and unloved. And the lower-libido partner is often equally distressed, both by their own lack of desire and the pressure they feel put under

In reality, for the vast majority of people, the desire to have sex is intrinsically linked to how emotionally connected they feel to their partner. 

My wife and I have slightly mismatched libidos that have become more obvious with time and kids (we're both mid-40s, I'm the one with the higher drive) and it can lead to frustration on both sides. 

She is now suggesting we take a break from sex for a short period to focus on rebuilding intimacy - apparently, this is called a sex sabbatical. Can this end well?
