Maybe you just need to try approach people differently or try meet people in different settings. I don't know how old you are or where you're approaching people, but it's worth remembering that even people without a stutter can be unsuccessful at this stuff. Shit like the Pickup Artist and incel communities exist because people find this stuff difficult. Again, don't get so hung up on your stutter that you forget to be a person. Talking fluently is not the secret to love.
