You've gotten some great advice, but being the know it all that I am, I have to add in my two cents as well.
I love my husband dearly, but he is just not a romantic guy on his own. Well, he is, but not in a flowers and poetry kind of way (see that five love languages book). He shows he loves me and tries to be romantic by laying tile for me, or scrubbing the floors.
Something that really helped us a lot was a book entitled "101 nights of Grrreat Romance". It had a bunch of sealed pages with great romantic ideas. Outside of the sealed page, there would be symbols that would give you an idea of how expensive the idea was.
Each Sunday night, we'd each pick a page. We then had until the following Saturday night to do whatever the page told us to do. It was a lot of fun to rekindle the romance.
I also think having a weekly date night is such a good idea. You don't have to spend money. You can go for a walk, go to the park, window shop. Make a rule that you can only spend 15 minutes talking about the kids, and then take the time to talk about other stuff.
Best of luck to you!
