Maybe she didn't get enough love from you? :shrug:
Tbh I understand your situation. I used to hit brother for ignoring me. >_>
That's a long story. The point is that we made it up, he ignores me less now.
Anyway, I'm sure she never meant to make you nose bleed and that she won't (that's at least what I think) say sorry unless you said it first.
Even though she is the one hitting you, she probably feels more pain than you have.
It's not like she is enjoying herself by hurting you.. There must be a story behind this. >_>
Going to go out on a limb here. My sister who I've been with my entire life slowly became a drug addict and an alcoholic that craved attention and if she didn't get her way on things she'd lash out and attack you, we both had the same problems growing up, we had it extremely hard, growing up in abandoned houses homeless shelters and just many, many bad things. Her bf got into a car accident, he broke nearly every bone in his body. He had a car laying on him. He recovers a bit after 2 months, he still has weak bones, partially broken still and not strong. It hurts him to walk. My sister is prescribed medicine that she abuses simply because she likes being high. Her bf manages her medicine because she will take too much if he doesn't. So she started beating him in his weakened condition because she wanted the drugs. Was she in the right for having a hard life? No, there is a point of sanity, a barrier, a line in the sand where you must be able to register that "This is wrong.". When you do not have that barrier, you are not sane, you are no longer with an ideal set of morals, you are only thinking for yourself and the priorities go Things you want>People you care about. Before that accident, she lashed out on my mom, she lashed out on my brother, she lashed out on her bf. I had witnessed this several times, it was almost an every day thing. I was taught to never hit a woman, I was taught to walk away. However, there isn't anything to walk away from when a person like that is someone you live with. She woke up one night, my sister had always been my best friend despite everything she did, she was the one person that I could relate to before she became unstable. I wanted nothing for that bond to be back again so I was nice to her as always and treated her no different than ever. She woke up, complained that there wasn't any food in the house. I told her I had two chicken strips in a bag in the freezer, it was my dinner but she could have it and I would cook it for her. Suddenly, she turned on me, right there as I was sitting in my chair drawing for an art project, talking to her. She came at me like she did to my other family members. She attacked me and suddenly, in that moment you think "If you let her do this, she will think she can do it to you any time she wants like she does to your mom, your brother and her bf who is also a good friend." So, I fought back, after she busted my nose, with my nose bleeding, I threw on the ground, slammed her hard, hit her, went to her computer that she was addicted to (I built the computer for her) I took it apart piece by piece and threw it all across the room and put her hard drive in the sink. She went from a girl that would beat my family members up, with them with blood showing all over, to someone that was actually too scared to do that again. It's not something that is a good thing, none of this story is and no one in it is better than the other person. However, it shows that people that lash out in violence, need to be shown that you will not take it. The people that cause violence can just cause violence out of pure ignorance. Effects that life has on a person does not make them a bad person as my sister is. When you cause violence to people that have shown you love your entire life, it defines who you really are. Also as a side note, I don't have the morals to be nice enough to let someone attack me. They hit me, by law I have the right to beat the shit out of them in self defense. However, if it was a wife, I'm gone. I'd just walk away.
