I had it once, I lost it though
And all along the fire below would rise
What's really going on below
I've lost you now, you let met go but one last time
The fire would sparkle in your eyes and mine
Just tell me you love, if you don't then lie, oh lie to me
If you don't then lie, oh lie to me
And call it true, call it true love
Call it true, call it true love
This one goes just after "Ink", so maybe she's stopped expressing what she feels for him because something's going wrong in the relationship. "And I wish you could have let me know" "Just tell me you love, if you don't then lie, oh lie to me". He just want to be loved by her because he really loves her and doesn't want to break.
I think he feels that his relationship with her is not real, he's not feeling like she loves him as much as he loves her. So he is mourning lost times where everything seemed perfect. Maybe something went wrong and now it's not working out, but they're both pretending it's all good.
He thought everything was going well but suddenly his partner left him. He wished they would’ve tried to work this out before it came to this point. He is reminiscing of when they were together and he still loves her, asking her to come back and pretend to love him back, which would ease his pain. He would prefer being with her knowing that she doesn’t love him instead of losing her.
