Should I be concerned?

I recently sent a text to this girl I’ve been dating for 8 months now a text saying that I want her to be by my side as I grow and that I hope that there’ll be an us in the future (we’re not official because we both have some things that we need to do for ourselves before we even think about a relationship)

She usually calls me when she wakes up but the past couple of days, she doesn’t do that anymore. So I called her instead and she told me that she read my message and that she doesn’t really know what to say and that we’ll see were things go.

With this response, should I be concerned? I can’t help but wonder if I’m just forcing my feelings onto her or maybe I’m just overthinking
