Started seeing this girl online, got dinner and drinks then slept together on the first night, stayed over/got breakfast etc. She was never much of a texter/flirt online but in person she was always very affectionate. The 3-4 dates were all within a week and did different things. After texting a decent amount (relatively) after the last date she barely replied the days to follow and now she doesn't reply at all. Any way to recover (fwb/dating)? and/or how to prevent this in the future?
