You become dateable by loving who you are first including with a stutter. One of the best things I’ve ever been told was to build your garden first and butterflies will come to you. I understand and empathize with you, I used to feel like if I fixed my stutter that maybe I could attract someone. But the truth is I needed to love who I was first before anything. I understand how hard it is, I am 24M and it took me so long to get to this point. But I guarantee you that you are worthy of love and very much dateable, you just need to tell yourself that first.
