How do i get my girlfriend back after cheating?

This is a really big issue for me me and my girlfriend had a thing for a while things always seemed to get in the way like she went out with one of my friends and cheated on him etc. finally months after we got together at first it was a lil bumpy and she always wanted to party and go and i wanted to have a serious relationship with her when she started going to parties i started uming she was doing wrong thing example cheating so i started doing it when she was partying i cheated about 5 times once with one girl four with another throughout the hole time of our relationship which has been six months. all four times were at the beginning of our relationship then things started to change and i soon realized that this was the best relationship ive ever had she started staying with me all the time we were basically inseparable and realizing the feelings in my other relationships were nothing close to this. she never found out about the first four i could never bring my self to tell her then one night she went out with out me and my friends ended up picking me up to go out after mygirl friend already went home and i got really drunk had with this girl which meant nothing and my girlfriend found out. the girl i got caught with was the one i cheated on her with four time thi sbeing the last and she broke up with me she asked if i cheated before i quickly said know not wanting to effect our relationship quickly she found out about all the other stuff i did. i cant sleep now ive been depressed and cant think clearly. we still talk its been about 5 days since she found out she tells me she needs time to get over it and i really want her back ill do anything, i know that while were not together she probably will get with some guys and its really going to hurt me. but im going to stay faithful even though not together to show her i will be different the next time. and that i wont even go out without her. what else can i do we still talk and text but she gets really mad and aggrovated with me jusst talking because shes disgusted with what i did. what should i do? give her space to think for how long? or should i still talk to her everyday if shes willing to and when she starts getting aggravated then i leave her alone?
