<human>: Can you condense the text into a few key points?

Hi fellas, its a bit long, please bare with me.

There is this coworker that I like and we are in our mid 20s. Our desk sit next to each other. I have known her about 6 months now we been quite close and we share a lot our world, families, education; the spark was definitely there but I got a feeling it was too fast to ask her out. To make it short, i did something that she doesnt like (i borrowed her stuffs like phone charger, ruler, without her consent) 2 times and she blocks communication with me on whatsapp, phone calls , even office chat.

After that we didn't talk like 2 weeks straight and she was literaly sit next to me, imagine how awkward it is. One day after that 2 weeks, she speak her first word to me and we talk again but its merely work topic. One time after that she called me around night time and we chat like couples, like nothing ever happened.

Here the thing is, she behaves differently to me now. I found her behaviour to be a bit bitchy to me now,she seems easily angry. Often if I do/ask something minor that she thinks its stupid to her, she become a bit upset and she said to me "talking to you makes my blood boil". But even all that, when we talk face to face there is this excitement between us. We exchange looks and lock our eyes couple times. And then she shoo me away,and the cycles keep on going till today. And yes she still blocks me on everything, except sms.

Its hard for me to fix this relation if she keep behaving like this, how can I ask her out this way, or even a short hang out dinner with me? Should I just stay quiet and ignore her? But now things are better compared to the 2 weeks straight silence that time. Honestly because of the quarel we had, I sort of like her more, something like I miss her. Its just she is not being sweet lately.

What happen to her? Please help me to understand her and how to fix this relation and possibly move it forward.
