How do I 22F detach from 23NB ?!? (This is my first real gay experience)

I started off looking for a casual relationship. I’m super busy with my band - we are building a following and doing tons of shows / other media etc etc. and I’m at the beginning of my career and figuring out my place as an adult in Seattle.

I’ve been on 3 dates with this person (23NB) and they’ve been amazing. We clicked, get along super well, have tons of shared interests and great sex.

We discussed recently intentions and they are still looking for casual like we originally discussed but I can feel myself growing feelings that are too strong… any advice for detaching in this situation? I don’t want to stop seeing them, and I feel like it’s early enough to fix this so yay we can continue in a situation that isn’t damaging but need to get ahold of myself. Anything is appreciated.
