How do you learn to trust someone after they get "emotional"?

It's mostly women I have this problem with, platonic or otherwise. I do something they don't like, then they fly off the handle, and then suddenly we're friends again like nothing happened? I'm sitting here scratching my head like "what the actual f***?!?!"

I try to keep my distance so I can process, but then they try to fix it and then as soon as I let my guard down it happens all over again. Any advice?
