Love subliminal not working

okay so every other sub has worked for me beauty ,luck ,money etc. but for some reason crush subliminals or love subs in general dont work if its for this sp I've been tryna manifest this person for 2 years I know I should give up ,which I have tbh but I just wanna know why they weren't working ive even done other methods to its just strange that I could get any other person but him ?? in particular to notice me ,am I doing something wrong ?
