I'm going to give an analogy that someone gave to me when I lost a family member.
It's called Box, button, ball.
Imagine a box with a button inside it. The button is your grief for the loss of your marriage. There is also a bouncy ball in the box. To start off with the ball is very big and pretty much every time it bounces round the box it hits the button and triggers your grief.
Over time the ball gradually gets smaller and as it bounces around the box it doesn't hit the button so often but when it does, it still with the same force and so your grief is big and painful when it is triggered.
More time passes and the ball bounces more gently round the box so that when it does hit the button the trigger is not so intense.
The ball will always be in the box and will probably hit the button for the rest of your life but the hits will become milder and more infrequent, until eventually you don't notice them so much.
Other life events can make the ball get bigger or more forceful again but it will reduce back when things are going well for you.
Grief is a such personal process that the size and strength of your ball will be totally different to someone else's. There is no right length of time or correct way to grieve.
Everyone carries their own box.
You are already so much stronger than you were at the start of your first thread and I hope you are giving yourself all the credit you deserve for how amazing you are.
