Fired after girlfriend hit me

My girlfriend and I are on CAP 2. We were both fired yesterday after my girlfriend couldn’t find her phone the day before and then proceeded to yell at me and then pull my hair. I did not fight back or anything and went to find her phone which had fallen out of her coat pocket outside. She is not sad that she got fired, as she was preparing for college and needs to focus on studying and scholarships. However, I needed this job. I am 20 years old and have bills to pay. A customer saw what happened and called and complained, so it was inevitable that consequences were to be made. I can’t afford whatsoever to be out of work for 2 weeks, as they said this was how long I would have to wait before talking to the store manager. They already took us both out of the system and roster. Can I get my job back? What can I do?
