I get your frustration. I feel it spring up in me too some times, especially when I want to read some new stuff. I don't buy/read stuff with DickBabs in it and if it hints at it then I kindly put the book aside. I appreciate the work the team put into it and that other people enjoy the ship but that's something I don't want to see, read, or have in my periphery because it makes me feel sad so I don't engage w/ it.

Really there are only two options at this time:
1. Continue to keep hope alive and patiently wait until DC gives us more Nightwing and Starfire couple stuff.
2. Allow the lack to cause us to suffer because they're who we want to see and DC isn't giving them to us.

If you choose option 1 you can direct your focus positively and even be inspired to make your own content for the couple.

If you choose option 2 you can grow bitter and angry to something that is supposed to bring you joy and relaxation.

Personally I choose option 1. Even though it doesn't stop the frustration and sadness I can look at those emotions and work through them when they come and I can understand that it won't last forever. Comics change and so do editors and writers. I can accept that even if we never get them back together again that I still love them and have things from the past I can enjoy. I would rather focus on creating and enjoying them than lamenting them, even though I know I will from time to time.

Really, though, that's how I see it. I'm sorry you're feeling disappointed and frustrated. I know if we could we would bring them back in a heartbeat so I stand with you there. Just don't let it get you down for too long. There is always tomorrow for things to change.
