DH and I have been happily married almost 20 yrs., and we have gone away without the kids for 2-3 days only twice. We would do so more often if we had trustworthy childcare, but my point is that you can still get little breaks and refreshers without going away and leaving the wee ones behind. When the kids are sleeping it's golden couple time. If we're wiped out we go to bed right after the kids, or at least cuddle and enjoy the down time together. We chat and connect as a couple. Very important for the health of the marriage! When the kids are up we take turns giving each other Mommy/Daddy breaks. An afternoon wandering around the mall by myself or with a friend without the kids is very relaxing and recharging for me. Work together with your husband to find something that works.
