Why is this girl ignoring me?
So basically, here's the story: there was this girl I found really cute so I got her Kik, so I first Texted her "Heyy" she texted back hi and we had a little Conversation. So the next day I told her "i'm falling for you a little" and again we had a little conversation. So here comes the problem, this random a*s girl came up in the conversation and said I was her boyfriend, when I didn't even know her, then the girl I had a crush on got mad and left, I tried all I could to get her back but nothing worked. Then I found out from someone, just say I love you until she responds and I did and she went like "lol :) i love you too". After that we had a good little conversation. Then after that I texted her, she read it but didn't say anything. So I texted her again and the same thing happened. I did this a lot of times(my bad) and all the times I did that, the same thing happened, so I got mad at her and said I was going with the girl that messed up our conversation, she got so sad and mad, but the thing is when I texted her she never texted back, but when I said that thing she went like "fine go with her idc" and it sounded like she was mad at me for saying that so it felt like she liked me, in a way. So all that happened I texted her and she went like "no, u said you where going to go with her". I really didn't mean it, I just sayed it because I was mad. Then one day I texted her then we got into a little conversation, a few minites into the conversation I want like "i wanna be your..." she went like " my what?" then I said " your boy....friend....." she went like " lol really" and I want like "yess". I got happy and said "you wanna be my...." and she said " yess :)" then I went like "hold, wait what?" then she went like "i wanna be your gf :'(" we have not talked since. I mean we talked little convos like "heyy" and "wassup" but that's it.
So my questions are: why is she ignoring me and why is it when I text her, she reads it but does not say anything back? And is there something I'm doing wrong?
thanks for your help, and sorry this story is so long.
