Please, don’t read into this.
If she says she doesn’t want a relationship, she means it.
Don’t think ‘Oh, maybe in a week she’ll want a relationship’ or ‘Oh, she’s probably just embarrassed because of how much she likes me and doesn’t want to admit it’ or ‘Oh, I can definitely change her mind.’
If you are having those thoughts.
Abort.
The mission is compromised.
Take those thoughts and throw them out the window.
You can’t do anything that will change her mind.
