wow i love this poem

it nails what betrayal feels like :D

i also really like your tone in the beginning, kind of furious and i like how you use "thou" and shakesperean language

however, one thing i would suggest is to keep that tone consistent because you later started to use "you"

unless your purpose was to make it sound like you were silvertongued then slowly revealed your less-formal self

for example in "hard spots i helped you throught"

the hard spots kinda knock the tone a little off

maybe try something like

challenging endeavors idk

anyways i hope this helped. keep up the awesome work!
