Any tips to rekindle a past relationship?

My ex of over a year now who i havent seen in over a year since i graduated but still talk to on the phone says she wants us to try and get back together again and i agreed and wanted to try as well. So one of these days we are gonna start spending more time together going out to eat and stuff you know the usual dating. Any tips on making sure we do end up together again? My feelings for her have become very dormant since ive been away from her so long but i know when we start hangin out more old feelings will rise to the surface so ill be hurt if our attempt of getting back together fails. Any suggestions?
