How do you respond to this without sounding butthurt? She friendzoned me then started trying to use me, helping her edit a paper she was writing, and I’ve now come to my senses and ceased contact. She’s the type who I believe will inevitably ask why I stopped talking to her. Of course the first answer will be “you don’t respond” and I get that but this girl and I used to fuck and I’d like to keep the door open for that possibility in the future, so I’d like to reply in some fashion.
