Broken things - broken relationships

I like to fix broken things which are dear to people. I develop creativity in how to do it nicely and enjoy the work. Is there a similiar way to enjoy fixing broken relationships? The things broke by accident, but did the relationships break by accident?
People make mistakes, but they also have misguided motivations.
I get very frustrated when the communication doesn't work. Not always people want a healthy relation. The appropriate relationship might be to stop relating.
