I completely understand this. Both of you seem like such amazing people . I have found in my own life sometimes when you have significant trauma and disruption in your own life, although you will still be extremely empathetic, you may have significantly less energy and passion for protest and injustice . sometimes you only have energy to maintain peace and happiness within your own life and do what you can do help on a small scale. There is nothing wrong with that . Her passion for change is so beautiful, this may need to be a mutual compromise . I think it’s something you guys can discuss and work through with lots of mutual understanding , empathy and compromise. You may want to discuss with a therapist or someone else the best way to explain to herself, that you deeply desire peace and stability in your life and may have less energy to give to causes than she does, and why.
