I picked girl up at a party, we went out once like a couple weeks ago. Before the date, she texted me fine and didn't take so long. Anyways, the date went fine. I saw a lot of IOIs and even kissed on the first date. The only thing I don't understand is that why she takes so long to reply if she's interested in me. We use whatsapp to text and I usually try to keep texting to minimum as we're adviced to, but I also flirt. I've asked her out a couple times too but she's refused cuz she's pretty busy with christmas and her cousins who come from abroad and I know she's not lying cuz she posts pictures of her with her cousins almost everyday outside doing something.
THE POINT HERE: Now, I text her and she replies fine in the beginning of the convo, but as we keep talking she starts to ignore and replies me back after a day or two. I know she ignores because of her last seen at whatsapp. Her reply after a day or two would be "Sorry for the late reply.." bla bla. Idk what this girl actually wants, how should i handle her? Should I let it go cold and then text her again or should I ignore her and move on? I kinda do like this girl and would love to escalate things with her. Thanks for reading.
