<human>: Can you give me the gist of the text in a nutshell?

i made the long flight to her. we stayed overnight in a motel. She was hesitant with sex at first, but in the end she was the one asking for it and we fucked. she thinks we're girlfriend/boyfriend now. I kept telling her that i can't guarantee that this will work out. 

I was kind of turned off because she had a bit of body and breath odor. It's terrible because i'm extremely paranoid of smelling bad myself and i keep thinking that's a reason why other people don't like me. It's most likely just a delusion but i have an obsession with trying to smell as good as possible. I feel terrible for being turned off by her because I know she has the same paranoid personality that I have and it'll devestate her if she knew that i was turned off becuase she smelled bad. She told me she has that fear too and she tries to shower a lot. But I didn't see her brush... when she came out of the bathroom her breath didn't smell any mintier like it should after brushing... 

But i'm just not clicking with her. Our personalities don't really click and i'm just not feeling chemistry. I don't want to hurt her though. She has the same mental issues that i have, except probably at the farther end of the anxiety and depression spectrum. Regardless, I understand her, i see a lot of myself in her, and i want her to get better. 

Is there any tactful way I could get out of this and stay as her friend without hurting her feelings?
<bot>: i had sex with a girl who is in love with me now and thinks we're a couple but i'm not feeling the same way
