Can anyone plz advice me on my current situation

Few days back i received request from my crush 's private account and i accepted it. In the beginning she was flirty but I being dumbass replied normal msgs . Then after this I asked her the next day that she wanted to truth and dare with me and this backfired badly. Now she is giving cold replies . Literally yesterday I said 'bye: and she left it on seen, then today at evening I msg her Hello and 'how is your day going' and she literally said 'ok' and left it. Now can anyone suggest me how can I improve the situation.
