I've been in your shoes in trying to rekindle an injured relationship.
First off view it as a fun challenge. While you have to put forth effort to make it work make it fun.
I like the book "his needs, her needs". It really helped me understand what my needs are and helped my girlfriend and I express our needs to each other. It was an eye opener to her how important a good sex life was to me and also how important other parts of our Needs are and how they all go together.
Next plan a date night. Maybe start every other week. Make a list together of the things you can do from just a movie or a coffee/book store to live music and a martini together.
You can also make a list of the sexy things you want to do together. Maybe a bit more adventurous stuff. Buy some toys, sex in new places, different rooms, in the car, etc.
The most important thing is to just do it. Just do some fun stuff and put forth the effort. You will see you both get closer together. The second thing is don't stop. Never never never stop. It's like working out.....consistency in your effort will really pay off.
Good luck and I hope you both have a blast!
