"Raising a hand to a woman is not the answer, stand up for what is right," writes Emma Murphy on YouTube.
The mother from Ireland says she's 26 years old and is now a single mother of two.
Murphy says she loved her partner with all her heart but with lots of "ups and downs," and she "will not miss the downs." She says she's made a decision, and he will not be around anymore.
"I'm a firm believer in standing up for what is right, if you or anyone you know can relate to my story get in touch," writes Murphy.
Murphy's video has since gone viral, even causing her former partner to publicly state he "is not a violent person."
