You've done an incredible job losing 110 pounds! I know that I am not at goal yet, but once upon I have been there. I just forgot the important maintenance step. Funny how that is important!
Lately you have been getting very close to your goal and I know there are a lot of stresses in association with that even though it is a wonderful thing. If you just started strength training that is definitely going to throw the scale for a loop, but it is going to be wonderful for the shape and composition of your body. Muscle also burns more calories at rest than fat.
Depending how much you are working out I would personally start focusing less on the scale and more on my measurements at this point. Losing inches is a wonderful thing!
But I need to ask. What does your goal look like to you? Is it getting into a size of clothing? Is is slimming down certain aspects of your body? Why are you not ready to stop and maintain?
