My own opinion is that too many people are constantly searching for that new, madly in love, honeymoon stage. Staying in a loving relationship requires a lot of active work. This includes in my case an occassional "why am I here" and "what attracted me in the first place" type of reflections.

Luckily now that the kids are older we have more time for ourselves and these minutes of crisis are few and far between. When they were small there just weren't enough hours in the day to get everything done AND focus on our relationship. I believe this is where and why many marriages fail. Sure there have been times that it would have been relatively easy to walk away, especially when Mr. New seemed exciting when you're bored, tired or just want to escape reality.

There has to be something there to begin with, you can't just pick some random person from the crowd and decide they're the one you're going to love. I think if you've had the chemistry and a firm foundation, love the one you're with. That loving feeling will return.
