Your partner can be dealing with inadequate pain control, medication trials, non-restorative sleep (fatigue), coexisting conditions, health care providers, family, friends, low self-esteem, stress, and medical and legal red tape. All this is exhausting for the fibromyalgia patient and for you too as a caregiver.
The best way for you to avoid burnout, and to help your mate be their best self is to not do too much. Two roles to avoid are “the enabler (you)” and the “victim (the patient).” Each of you should focus on what you CAN do, and both of you should keep the lines of communication open, while understanding that sometimes both of you may need to let your partner know - you just need to talk about your day.
Always keep in mind that some things cannot be fixed, accept what is, and always look forward. Both of you are learning to deal with the associated losses of having a chronic pain disorder, your new task is to find ways to replace losses with gains; this is the way both sides of the same coin flips.
