situation with ex

Was with my ex for about 18 months and after a few really difficult times it ended quite badly a few months ago. We had no contact for a while in an attempt to both move on (which has failed on both sides). My ex recently got into contact with me and we spoke a while, both apologized for the things we had done wrong and it is fairly obvious that we both still have feelings there after everything. However I am unsure what to do, whether to suggest talking things through more and possibly sort things out or how to totally move on and away from what we had.
