Missing someone out of habit isn't true longing.
It's a commonplace misconception of your emotional state.
Nostalgia of what once was, placing focus on the potential they once had.
If it is constrained, if it is self fabricated, it isn't worth your time nor energy.
Loving someone out of comfort isn't love at all.
It comes to a point where you must accept that you are worth the love you omit to yourself.
In the grand scheme of things, it doesn't matter if they ever loved you at all.
In the end,
all that truly matters is one thing
...
You
have to
love you
first.
