Why can’t you let me let go?

That’s what it really comes down to, I want to know that they will be okay without me but they won’t let me go.
It’s ironic considering I feel like the side character in everything, I’m not the loved one, not hated, just there, in the background and forgotten, playing a role that doesn’t affect the main storyline. Not the person you think to invite to any occasion but might be there with someone more important. Why won’t you let me let go?
