Forbidden Love

Okok so this is the second poem in my horror trilogy. It's a 'place poem' or whatever, it was originally supposed to be about a place you would like to return to and how it made you feel. I don't like following the rules when it comes to poetry and so now, I have Forbidden Love. There's a little disclaimer at the end btw. Hope you enjoy! (P.S sorry for the formatting of the first line, idk how to fix it.)

Deep in the ground, surrounded by hot, heavy air,

Dripping with sweat, my helmet light flickers.
Suddenly, the pathway in front of me becomes alien,
As darkness seizes its chance to strike.
My breathing echoes, creating a yearning song that only she can understand.
The wet ground squelches under my boots, and I hope she knows I don't mean her harm.
Water splashes into puddles, from stalactites up above, and I hear her calling out to me.
My headlight, running out of battery, illuminates narrow cave walls, her way of touching my skin.
I place my hand upon the rough stone, to let her know I understand.
I reach the center now, a large cavern, her heart.
I lower myself down a sharp embankment,
Digging my fingers into the soft dirt and begging her for strength.
My feet slip, and my breath hitches. Not yet. Not here.
I finally reach the bottom and lay on the floor of her heart.
I used to come here for fun, not expecting a lover.
And when I found her, I knew it was destiny, that I should be the only one so brave as to know her.
To love her.
And after I return this one final time, and my darling cave claims me,
I doubt anyone will do so again. 

Disclaimer: I don't like Forbidden Love as much as my other two poems. I do love it, but I feel like it could be better. Any constructive criticism is welcome!
