Pretty new to TRP but getting there

Anyway a girl i met a few months back but had a BF at the time, there was definate chemistry and she contacted me a lot and we talked and flirted a bit but as she was taken i didn't persue her and let her drift away

anyway a week ago she broke up with the BF and started texting me. We went to the same house party on the weekend, long story short hooked up, back to mine.

In the morning she hung round for a few hours then left, texted me later that avo saying she had a real good night etc etc etc. I just kept it short and sweet.

next morning she texts me again asking if im ignoring her?

I was like nah just busy with work etc and dropped some banter but now she seems mad at me or something... and the old beta me would be like "whats wrong" etc but since i'm trying not to be a beta obviously im not asking that. But i do wonder if im being too cold or something?

I do like her but i kind of assumed since she is still working through the breakup that just having fun and not being too serious would be the correct move and just see what happens, like i was cool with being a rebound or whatever... but i dunno what she wants haha

as i say new to all of this so just wondering what's up here.
