Hello! I went to a social event last week and got talking to this girl. The conversation went to about 30min and pretty deep, like my life story, hobbies, age etc. I even got invited to her city. Good eye contact, proximity. In the end we exchanged emails (not social media) and said good bye. It didn't strike me to ask fo socials at the time but I'm now interested in her. I've emailed her but haven't heard anything in a day. Was she being friendly or was she actually interested in me?
