I thinks all relationship are based on acceptance of each other thoughts, beliefs, ideas etc.
When there is no acceptance is from any end that might be a last hammer on relation until it get corrected within time.
It simple to say "move on" but how can anyone do that without any effort they have spent plenty of memories and moments together.
Time is the only medicine that can work but it heals properly. You have to spend time to explore yourself and keep the schedule hactic so that u can forget wt happened.
Other option is find the person whom u can share your fellings and express them in front of them it will surely work for u confessions are best way to lite ur mental burden.
