Thought i'd share this thought......
if you are afraid of your relationship failing because you dont love your spouse, then choose to love him/her. I read this on Steven Covey's 7 Habits book sometime back. Had a recent crises of my own and i said to myself i chose to love my (gorgeous, wonderful, caring but boring) hubby because he is the one for me for various reasons (all noted down and thought out).
.............in case it helps anyone in a similar crisis.
