Anyway this time we got back in contact when I apologized about the last fight we got in and she responded "I appreciate the kind words. You're a really good guy, always the first to apologize and make things right. I'm sorry for everything. There are no hard feelings :)" I realized after she re-added me on fb that she just got cheated on by another guy and I cheered her up and she told me "<3 I appreciate that a lot. I really needed to hear that."
A couple days ago she added me on instagram, I don't have any pictures posted. She texted me "post stuff on instagram so a can creep on it :)". After a couple more texts she was telling me things like "you're my favorite" "Let's start over again, I want to see you" and "I had stopped myself from texting you like a billion times, I think about you all the time"
She ignored a couple of my texts two days ago and then randomly texted me randomly just now completely ignoring the two texts I sent her saying "How tall are you?" I responded and asked why and she said "Curiosity lol"
Today is her birthday so I texted her happy birthday and she responded "<3 <3 Thank you!" and I also wrote happy birthday on her fb. Of all the happy birthday posts on her fb, mine is the only one she has liked so far, and she also commented on it.
Is she playing games with me, am I like a rebound for her and she is coming back to me because another guy just cheated on her, or is she realizing she missed me/wants me back?
