Welcome to the forums!
If your daily contact is on friendly terms, could you ask to discuss the issues to determine what went wrong in your relationship? If you are both willing to make adjustments there is a chance you could reconcile. Asking to talk about the situation with him could help to determine his true feelings. You both need to want a reconciliation in order for it to happen. Regardless of the outcome, a discussion might help to give closure to this situation.
Best wishes,
