so heres my situation.... this girl randonly imed me online and she is in my class...so we were talking for a week, i asked her to hang out with me to come to a party a few times and she always said no. she said that her parents didnt let her. i gave up on that and all of a sudden we stoped talking for like a week. i didnt pay attention to her at all and a couple days ago she started talking to me again. i didnt make it seem like a big deal that she didnt speak. so we texted all the time and spoke alot. i invited her to a show and she went but an emergency came up and changed all my plans so i didnt go.. i told her that im gonna make it up to her and when i asked to her to hang out again she gave me the same excuse.. now its dead again , we barely talk and dont text her no more.....i still say hi and bye ....but its not the same...
wat should i do? how can i get the spark back....? situation sux....
respond...tnx

You fucked up by apologizing to her for not showing. On the other hand flaking is messed up in itself regardless of the reason.

Anyway, give her space for a few days, then re-open her. Do an actual opening on her as if you didnt even know her...it will be funny. Start building back up rapport from there.
