im feeling disgusted by my closest friend for the dumbest reasons

I don’t really know how to start this off. But I should probably start by saying I’m most definitely asexual/aromantic. I’ve never had a desire for a relationship or a partner whatsoever and the thought of being known as someone’s ’girlfriend’ literally makes me sick.

I’m really close with a girl (MTF, let’s call her Jane), and she most definitely has feelings for me. Talking to my other friends, they mentioned to me that she had admitted it more than once and it was obvious in the way she acted around me, anyone could see it. Except I feel nothing for her but pure revolt.

She keeps trying to touch me and be close to me and it’s starting to make me feel sick to my stomach; even hanging around her makes me feel dirty for some reason. I’m actually disgusted by her for no reason. My feelings on her have completely shifted and she went from “kindest, generous best friend” to “overweight, greasy, grabby furry” really quickly.

I have sexual desire; not romantic desire. And she is the last person I want to be in a relationship with, whether that be sexual or romantic.

I feel like I’m leading her on as well. She’s my closest friend and I’m starting to lose respect for her quick because I’m a self-loathing hateful prick when it comes to relationships.

Does this have a name? I don’t let anyone get close to me romantically, or even as friends. Is there something wrong with me? Can I fix this??

Advice would be appreciated, thanks
