Me and my ex got into a fight again after recently splitting. he blocked me on everything. I blocked back. is there a chance of reconciliation?

We were together for a long time , and have to see each other everyday. Is this something that can resolve in time? Or is it completely ruined?

I don’t necessarily want to be back together but I want to be friends and we just can’t seem to work it out. He also seems confused with his feelings because one week he misses me and wants me back and I decline, the next he’s angry with me..

He also seems like he’s trying to hurt me by making comments that he’s so relieved and happy we broke up but if he was so happy he wouldn’t have these big mood swings concerning me
