I still like my ex... what should i do?

So ill just give some backstory. Me and my ex broke up awhile back ago but then a week or so we got into a huge fight about something stupid. But i still like her and yeah. I did the basics of apoligising and saying sorry but she un added me as a friend on fb and snapchat and stuff.

so how should i reaporch her and begain talking again and convicing her that im cool. And become friends again
