AIO: Heard this song and dance

Woke up to this message from a girl i’ve been dating for a few months. She’s currently on vacation visiting family so i haven’t seen her in a while. Before she left we had a conversation about what we wanted out of this relationship. Me basically saying that if you’re not trying to make something real out of this then we should just leave it alone. She said she wants to build something up and see what we could do. While texting and calling her we talked about how we missed each other. Then i get this message and (as you can read) i was conflicted on how to respond to her cause it just seems like straight bullshit. if you’re not there mentally or emotionally then what the hell do i want with your friendship? Whenever i’ve heard this before the truth is they’re not over an ex or simply not interested in the other person, which interest never seemed to be a problem when she would “beg” to see me before. I just don’t understand the temperature change and don’t want to be an asshole by telling her to fuck off. my main thing is i’m not going to sit around and be on a back burner and be your friend if that’s not what i want. I also don’t know how to express this without sounding like an ass, i typically say it how i see it. Any input from you all?
