Dear OBB readers: How do you bring the spark back into a marriage?

From a female OBB reader

Please I need desperate help. I've been married for 8 years but the spark has gone out of my marriage. My husband used to be so romantic but his priorities have changed since we had our four kids. Its now all about work and children for us. We haven't gone on a dinner date in years. We don't even make love anymore whereas in the past we couldn't get enough of each other. I'm trying to rekindle the romance in my marriage, please any suggestions? Serious replies only, please
