I think I would replace scar tissue with known limitations of the other person. You can learn in a long term relationship you can trust a person in certain ways and not in others. You learn you will be fulfilled in certain ways but not others. Long term relationships work out of accepting limitations. There’s also plenty of examples of long term collaborations in business, so I’m not sure the underlying premise is solid.
