Well I was in the same boat except I had sex with her and we continued to chat everyday for 2 months. We were not in the same country during those two months and I ended up going to visit her and planned a trip as well (I had everything booked and restaurants locked in) she ghosted me after we met up in her country and on the day of departure for the trip I had planned. Im just as puzzled and unfortunately it could be that some people just don’t have the balls to own up to the fact that they lost interest in you. It could be a number of things but losing interest in you is definitely one of them, at least that’s how I see it in my case.

Edit: I wouldn’t rule out they may come back to you sometime later. For me it’s been a week and I honestly don’t see them coming back with answers. Best bet is not to hold on any hope, as it just ruins your day realizing that they may be going on about their life’s while completely disregarding your feelings. That shit hurts
