You may want to watch it carefully as it may not be finished. EC-1118 has an alcohol tolerance of about 18%, and you've fermented to a little less than 14% ABV. That means you still have potential for the yeast to go farther with the residual sugar that is there. Without more recipe detail I can't say for sure why it stuck there (although you did add a lot of acid), but it might continue plugging along very slowly with no bubbling visible and only a gradual drop in the gravity over the coming weeks.
Don't be in a hurry to bottle it unless you stabilize it with sorbate and sulfite.
