Why would this girl (my ex) and I always end up taking a more romantic turn, even if we're trying to keep it platonic?

Also, would it make sense that she'd keep space to heal from her old relationship? Especially given what I mentioned before, and the assumption that her being in a relationship could be detrimental to that healing? (But her keeping my contact on discord can be an indication that she does plan to loop back in time?)

(Her and I dated for a year. Broke up, but reconnected a couple times. Each time we'd either start treating it like a relationship again, or would end up dating. No mater if its 1 month of nc or close to a year of no contact.)
