Along with the therapy/counseling, you may want to check out the book, "The Five Love Languages" by Chapman. It's been referenced here in lots of threads, and I'm sure it's in our Book Recommendations sticky. I thought of it when you mentioned having taken her for granted and not connecting the way you had. maybe you both have different needs around expression of love and feelings, so if you know what each of your dominant love "language" is, it might help.
The world opens up... when you do.
