Long story short, after years of friendship(and secretly love from my part), my best friend revealed she liked me back. We started sort of dating with kissing but no sex(close though, this all happened a short slump of time), but then she needed to move to another city.
As tough as it was, things were going seemingly smooth, talking a lot, calling each other love, honey, babe, when we would meet again, living together in the future, all sorts of stuff. One day she said she'd be weird for a while, considering the different city and accommodation period, this made sense, but now all of a sudden, she started once again only calling me friend or buddy, talking quite less and mostly killing my conversation approaches/compliments. This change happened in less than 48h, I didn't do or said anything odd and she didn't mention anything either. Should I worry about all of this ending before my eyes while I couldn't notice? Should I do something?
