What is this?

I can feel it inside my heart, exploring every crack and wrinkle. I held his hand for so long and while it seemed weird, I couldn't understand why I couldn't bring myself to let go. Something inside me wanted our hands to be joined together for eternity. I didn't want it end yet I knew I had to let go before I did something I would regret. No matter what, I don't think I could handle him flying away. As much as it would be better for me, something inside him is mine. Something inside me is him and oh how I wish he knew how much I've tried to change for him. To become the person that my angel can be happy with. I wanted nothing more than to have him hold me close in sweet eternity now, it seems it's just a privilege to know I'm breathing the same air as him. It's hard to understand but it all makes sense in my head. Can I let him go? No, I don't think that's possible. If he ever left this world, I would chase after him even if he would never be with me, I just want him to know how much I truly feel for him. All that I am, my being, is his. Every breath I exhale, is for him. Every tear I shed and laugh that comes out of my mouth, it's all for the chance to see him. I'll never feel this ever again in my life and I want to make the most of it. I want to hear every word he has to speak. Every pulse in his veins, I live for them all.
