Sometimes, after a relationship, you don't want to completely cut the person out of your life.
Especially if there was a friendship before you dated.
It's nice to support each other, even in small ways.
And it feels good to end on amiable, mutually-respectful terms.
Although sometimes a friendship can't happen right away.
And it shouldn't necessarily be forced if the breakup was rough.
If you're dating someone who is loathed by all their exes, that might even be an important clue.
And might save you from a toxic relationship.
It's not always the case, but it can be nice to remain in an ex's life.
Because we've all done our best, and sometimes the next step is friendship.
