i took some of u guys advice and did what i had to do.

I talk less to her and focus my work, I don't show much initiation and didn't give her attention at all.

After few days past, she's been all flirty and talks to me very often and she makes a lot of effort to talk to me, but I just gives her normal answer.

Then recently she asked me why I have been so lansi(action), I guess she sees that I talk less to her and my behavior bother her, I just told her that I have been very stress lately, like work.

Then after tmr, My colleague who knows whats going on to between me and her, only he knows, the rest office colleague don't know. He informed me that she asked about me, the way why I had been so strange toward her.

Today, she's been acting even more strange, she's been mimicking my behavior and my colleague point it out to me. Geez, this woman can't let me move on is it?

Also, whenever I have conversation to her.

Me: so, you and your mom go out la?
Her: what do you think? DATING with my mom?
Me: huh? I don't mean that le..

I was like no need to RUB it in my face one...I really got offended. There are number of time where she disregard my feeling... =/

No idea what i need to do... help?

From my point of view, no need to confess twice to gives her the satisfaction of validation or stroking her ego. IF she ever confess to me, I think I would think twice before accepting her into my life. Will she bring happiness into my life or will I be the one who needs to constantly validated her ego. I look into mirror and be honest to myself, since she don't have any experience in relationship, I would be the one suffering but the question is.. will she learn how to be in a good relationship, will she sacrifice her work in order to be with me? Relationship needs each other help and create balance, that's what i see in a relationship. I really do not want to be her emotional tampon.

Update:

Haiyoh, what a terrible day I am having. Today, I tried to confront her that her behavior toward me is unacceptable to the point of work related is involve, I cannot tahan anymore and need to solve the problem. She literally mimicking my ACTION,  like whatever I said in the past that I "subconsciously" hurt her feeling, come bite me in the @ss.

She also apologize to me but I can see it is not sincere at all, she is very spiteful woman and told me I am super sensitive, I am like I am just expression my emotion and wants a mature conversation with her. Whatever I tried to says something, she always cut me off half way then assume that I am judging her, I am like no... I am just having an adult conversation only... cause I want to fix our work relationship. Communication with her is so hard, I pointed out is it bothering her? She says no. Then, she always talk about her behavior and her feeling, and don't really care about my opinion or how i feel. When i talked to her, she is very defensive, I gave some body language, she pointed out that I am judging her. wtf! Also, she remembered everything, she finally comes out of her shell and tells me why i didn't do this, why i didn't reply her text message and etc etc... the part where I didnt reply her text message is because I was sleeping the whole day and the day after tomorrow, I checked my phone, and somehow forgot to reply her.

I am like o...k, so we don't have any problem, she says no we dont, and gives a false smile. I am trying my best to salvage our friendship but it seems that it's already beyond saving.

what to do.... i am thinking writing a letter to her =(
