help

okay so I been leading this boy on for weeks now and we been hanging out but he has feelings for me and I don’t but I told him I like him because I don’t like to reject people and make them sad but I know I’m gonna make them even sadder when they found out the truth but the worse thing is that I’m starting to like his best friend 😭😭 I get butterflies when I see him and I don’t do that with the person who likes me. I don’t know what to do, the person who likes me spend so much time on me and is way more better than the person I like but I don’t feel the spark when I’m around him but I do to the best friend so please help me.
