So my girlfriend "Lily" hasn't texted me in over a week. I can tell she is alright and receiving my messages, as it says she has read them, but she won't respond, even if I send something romantic like "I love you" or just say something like "let me know when you can hang out".

Lily is usually busy and will text me "Sorry can't talk right now" and that will be the end of our conversation. My friends, however, said that this is suspicious and means she doesn't WANT to talk because if she couldn't talk right NOW she would at least answer later instead of just reading it. ' I have no idea, it's been a week and I haven't heard from her.
