It doesn’t go away completely, but eventually the time comes when you learn to coexist with it. I keep some of the things that used to belong to them, the things that hold a happy memory. When something reminds me of them, I acknowledge it, I think, “oh they would’ve really loved this.“
It’s easy to push the memories down to try & avoid feeling the hurt, but the only way out is through. Sometimes it’s enough to just remember that they were there once.
