so I went to a party recently, met this girl, she is beautiful, we talked a lot, she showed a lot of interest (i think), we kissed a couple of times, she wanted my snap so i gave it to her. Next day we text, everything is good, she replies decently fast (often around 10-30 mins between), then that night i text her if she would like to meet again soon then she took around 15 hours to respond but said she would like to, i asked are you available someday this week? she said that she was quite busy but might be able to make time for something. i texted back "okay, what day is the most probable one to meet?) and then she hasnt answered for like 10 hours.
Listen, im probably overthinking this, its my first time talking to a girl. Is this normal? or am i just overthinking everyting? Now that i see what has happened in writing it doesnt seem that bad after all but i cant stop thinking about her. Im 17M she is 19F. Am i moving too fast?
