Gently rejecting?

Hellooo need some advice. I have this male friend who completely felt for me. I never trusted men/women friendship (I’m old school) but life put us together and I tought he would never fall for me since I’m really weird (Aquarius here🫣). I’ve tried all turns off so he would not find me attractive anymore but nothing worked🤧. I wanted him to be turned off so his heart wouldn’t break ( I put my dignity to trash to turn him off😫) but I’m desesperate I just lost the control and I feel he is so in love …he wants to see me again this week and I wasn’t able to say no😭 please how can I make him understand without breaking him🥹
