Question about a restraining order

My sister and I would like to get a restraining order against my ex's girlfriend. She has become confrontational towards me and has been verbally abusive towards me several times. Another incident occurred today in which she got right up in my face about an inch away from my nose yelling and cursing at me in a public place. I told her to stop but she continued. My sister came and intervened and she shoved my sister so hard it threw her several feet as she tried to keep her balance. I am wondering if this incident is enough for us to both get restraining orders against her. We are both afraid because she continues to initiate this type of behavior and we want to put a stop to it. Please advise. Thank you!
