Have been chatting to this guy online for a few weeks now and we went on a first date today. For context he’s 25 and I’m 22(F). We went for an ocean swim, got some food and then called it a day. I had a really great time, he’s really sweet and seems like a genuine guy. The date was a lot shorter than I expected it to be, around 2.5 hours (is this a normal amount of time??) but still I am definitely crushing on him. Do I message him first and thank him for a nice time, or wait for him to reach out?
