How to Move On

People have certain things they do in order to move on from their past relationship.
They either clean the house, make it look different,
full make over of themselves,
shopping,
eating a lot of ice cream,
going out with their friends,
reading the bible,
be with their families,
work out,
have sex with different people,
have a new relationship,
and more...

People do all that just to get over their ex...
But what if your ex is everywhere,
you hear him everywhere you go,
you hear him on the radio,
you hear him on TV and the internet,
your other friends talk about him all the time.
Now, how can you move on from that?

Would you accept it, the fact that he's going to be around whether you like it or not?
Or
Would you run away as far as you can and start over?

What other options do you have to move on?
