okay I obv don't know the context here but I will say that a lot of people in toxic relationships try and justify awful things through love. No one leaves a toxic relationship because they don't love the other person. It's because they love themselves more.
If your partner has ever laid their hands on you, scares you when they are angry or threatens you, they are a violent partner. In that case, you need to leave the relationship before things get worse.
About reporting them, that's not for you. It's for other people. It's to help other people avoid this person when they're doing a quick background check before their first date. I would never let someone I love go on a date with someone with a history of domestic violence. If you feel that your partner could hurt someone as much as they have hurt you, please do report them and save some poor girl from a life of misery and violence.
Your family loves you and is trying to protect you. Please don't mistake the highs and lows of a toxic relationship for love. And please don't ignore the people that are trying to protect you. I hope you make the right decision <3
