Species Orchid, Dendrobium, Parish's Dendrobium

HELP!

I have had this orchid for about 3-4 years now. And I agree, the flowers scent is intoxicating...I describe it as "...Read Moreit smells liek heaven".
However, I moved into an apartment about 2 years ago and it only flowered once (when I first moved in) and it has not flowered any since. It almost looks dead but new stems continue to sprout. They get about 2 inches and just stop and get that brown paper like covering.

I only water it about once every couple weeks. I have pictures of it if interested. Please let me know, I miss those heavenly flowers!

If anyone knows what I am doing wrong or what I need to do, I will take anything! Thanks!
