I lost my partner back in may
Lost in what way?
He didn't love me back, I should have never dated him to begin with.
It is understandable to be sad when a relationship does not work out. It is better to move on than be stuck in a bad decision.
I've accepted that I have to move on, I just need some time to grieve his loss.
Then your mind is in the right place and I applaud you for recognizing that you need time.
