I don't know what this feeling is

I'm lost I don't know what it is do I miss him his presses his thought his gaze the way he holds me the sour of his voice the sound of his laugh what is it that's making me feel alone right now I want to feel the warmth of his skin on mine to feel his breath on the back of my neck telling me so sweetly how he loves me wanting to fall asleep wrapped up strong arms knowing the strength they have but feeling the gentleness in them so can you tell me what this feeling is
