Romantic Relationship Ends - Become Friends and Safety Nets !

You can only pull someone up for so long before it hurts both of you.
Sometimes it’s best to allow people to stand on their own,
being there to catch them if they slip. ~Nick Mansilla

Even though not in romantic relationship, you can remain good friends and become safety nets

And it is usually a no-fault situation - too complicated to pin the problem
on the spacer or spacee!
