I can really relate to your disappointment Yack. When my husband was stuck in a depressed episode, he really felt like a failure because he couldn't afford to buy me a nice ring. At the same time, I was really scared that I was supporting him all that time but that I was perpetuating that cow/milk thing. I truly didn't care if all he gave me was a rubber band for a ring - or, he could have drawn one on me with a sharpie - I just wanted a gesture of where his heart was.
So, I understand your disappointment and my heart goes out to you
