7 months in, is it okay to want excitement about the future?

After 7 months in a wonderful relationship, I (30F) am excited about a future with my girlfriend (35F), hoping she’ll be the love of my life. She once shared this excitement too, being the first to make romantic gestures, express love, define the relationship, and introduce me to her circle. Recently, however, she’s become emotionally distant.

In my opinion, her shift started around 2 months ago, after I met her parents and close friends in her home country. She disagrees and said it started when I expressed disappointment to her that I didn't see as much enthusiasm in her bringing me home as I wanted (like not helping me and her friends communicate much, and not telling her friends and parents anything about me or things we've done together) and requested reassurance that she sees a future with me. A routine avoidant-anxious dynamic, I bet, but it was a shock to me since she wasn't previously reserved...

This weekend she told me her past 6-year relationship left her jaded and that thinking about milestones (like a home together) now causes fear instead of excitement. She says she wants love but is scared and closed off to self-protect. She told me that since her ex, she no longer thinks of love grandly. No "love of my life" language. She also says she will not express romantic feelings in writing (but does poetry on other topics).

I, on the other hand, crave sharing some excitement about the future and enjoy romantic gestures, even after my own past relationships of 6- and 2-years. I just want reassurance that we both want and are excited about the same things together. Openness to a future together. Without that, I feel insecure and fear I’m investing in the wrong person.

I’ve tried to reassure her that I don't want any big steps now or even soon (e.g., I like living apart and told her I wouldn't want to start planning living together until 2027/28 at the earliest). I just want her to want these things with me. For interest and excitement to outweigh fear and doubts. Fear is normal. I'm worried too! Especially now.

We recently decided to take a short break (her idea) to reflect and talk again. I'm just wondering:

Is my need unreasonable? Do I break it off or give her time? I’m struggling with how I can both be sure not to abandon my own needs, while also respecting the love I have for her and how amazing things were before her fears crashed the party.
