maintaining difficulty

happylife1

hello, so i am 5'4" and have been eating 1200 calories for a long time and workout anywhere from 4 to 6 days a week. i have now stayed at the same weight for 6 months or so. i want to maintain now, but everytime i go up in calories i start gaining weight, even when i dont eat all my maintaining calories. and i dont want to have to only eat 1200 calories forever. Any advice from anyone? i am trying to maintain 117.
