Taken out of context

So last week something happened between me and my cousin who's a mother and she jump to the worst possible conclusion of that I harmed her child on purpose which was taken out of context because she just assumed that's what happened and has been pissed off at me since and it hurts me to the core that my family would think that it would ever happen

So my question to the mothers is if something happened to and you assume that someone hurt your child on purpose and didn't get the whole story and took everything out of context

do you ever truly forgive the person that you're putting your blame on even if their family or would you always hold that anger and resentment inside you even though deep down you knew that the person you're putting your blame on never ever do something that you're accusing them of doing
