Tinder girl
I Need Advice
Hey everyone, so I’ve been talking to this girl i met on tinder for fifteen days. I don’t think her nor I used tinder often. So this girl i matched up with is really chill and seems nice and smart. We went on our first day last Friday, and we went to the mall and then the movies. During the movie she tried to make a move on me and kiss me. I had no idea what she was doing so in my mind i thought she was stretching and continued looking at the movie. She is a smart girl, so i thought she was gonna wanna take it slower. Okay so that happened and a few hours later i kissed her and then afterwards she told me she tried to kiss me in the movies. And so this isn’t the type of girl to reply within 1 minute. She usually takes 5-15 minutes, and honestly i think she ducks our agreed phone calls at night and “falls asleep”. Tomorrow is gonna be our second date, and i really like her. She has never been in an official relationship or anything, and i was wondering when would be a good time to kinda hint at being exclusive? And what signs should i look for ?

I genuinely believe she has a nice heart. Thanks
