Hello .......
Virtually all of us have lost a love. Nearly all of us - more than once. It's never easy. You can't expect your feelings to just go away by themselves in time. It rarely happens.
What too often is the case, as an example, is one person hangs on never really dealing with the loss ... and maybe temporarily getting busy enough not to think about it!
So ...... it keeps coming back. I know of one person who kept doing that for 19-years! She never did deal with that loss .... and died without having that peace of mind - much less being able to move on into a different relationship.
We all need help getting thru those difficult times. It's usually best thru a professional - like a talk counselor.
That has been mentioned here by several people - including possibly where to look.
Please seek that help.
