These both apply to romantic and platonic relationships.
Genuinely apologizing promptly after a fracture makes a huge difference. Avoiding it because you're conflict-averse or self-loathing will make it into a much bigger deal that is harder or perhaps not possible to repair.
When someone tells you that you've hurt them or behaved in a way that is unacceptable to them, it's not an attack on you, but an act of love and trust.* If you don't care enough about someone to stay in a relationship with them, you leave or fade out. If you do, you give them the chance to apologize and grow.
*Not applicable to abusive relationships.
