Like a kid with many toys

The avoidant discards their partner because they do have a lot of toys (people they want to date instead).

They’re sick of their toys easily, and it doesn’t require much for them to get sick of their toys either.

But the toy must always be there within grasp. They might not like that toy but will get affected if someone takes that toy they’re ignoring. That’s why the avoidant goes back to you sometimes or dangles you with a leash.
