how to get back with ex?

I really love this girl.. We went out for over a year.. she tells me she loves me too and didn’t want it to end but she just feels its right.. I don’t know what to do.. I told her everything i could.. I need her in my life she’s perfect to me.. I really love her.. I just wish she was back with me.. How would i ask her to come back to me? any sweet ways or something so she would come back to me?
