Let me tell you something important from another artist i know that had a hiatus issue.
You need to ask yourself if you want to go back to it, it really dosn't matter how much other people do or do not want it to come back, it depends on if you want to bring it back, no matter how long its been since the last ep. If you find yourself working on the next page and just asking yourself why you cant put the pen to the paper and the answer you have is "I just don't want to" then maybe its time to let it go, but if you start another page, and then another, and then another, then you shouldnt worry about if other people want you to bring it back and realize that your ready to start it back up again.
Sometimes a hiatus can end things for you completely, but sometimes you just need a break (however long) and come back refreshed.
