Spoke to a girl via insta and Snapchat.... she added my snapchat, conversation was going well, then the subject of conversation went to, what do you want etc, and she said something serious not just sex. And I said why do you think I’m a fuck boy kind of guy? Then she just ignored every message and the eventually deleted me? How can it go for 100 to 0 instantly? I feel helpless on people’s perception of me, what can I do? It puts me of dating in general

Opinions on how to improve my dating game I’m 20 years old Thanks in advance
