youOme: We were happier during those times and loved each other...or so we thought.

Between you and your husband you have young children, college/work, and a home to care for. All that takes time, to the extent that there's none left over for each other. The love that you once felt for each other is probably still there, it's just been neglected.

I suggest you review some of the material at the following site to see if it might be more effective at bringing the love back into your marriage than a baby would.
