CNY is coming and she says something like if she manages to come back from her hometown (Perak) on time, then she will accompany me to visit my relatives/friends houses...I was quite surprised and never expected this from her though.

Is this a good hint or just another grey hint? 

This morning she suddenly texted me and asked how I will introduce her as when she visits my family. Then I casually and straightforward said as my gf for sure then I ask her the same question back. She was shocked and she said she will introduce me as a friend to her family. I sent her a sad emoji and she responded the same. Then, I said I'm being sincere here and if it's too fast pace then I will follow your pace. She replied back by saying normally she will bring the guy back to see her parents before decide to become life partner. Then I told her i don't seek others' opinion or approval to decide my life partner because I believe in my own evaluation. She said this is her traditional way to involve her parents in big decision and I responded that I will follow her way. She ended this topic by saying this is just a normal chat not hinting you something then I just let it slides and end it.

Introduce as friend first before as boyfriend to parents is normal nowadays?

I definitely need to slow down but for me meeting parents is only when both are official as a couple though...

she is hoping to jump ship ... maybe as she is repeating the process of texting someone but to the different person this time (u)... so u also have to prepare for the worst that she might be temporarily using you ...

example : iPhone 7 hilang, so temporarily use u, the iPhone 5

Just a small update:

She still uncertain about whether I'm the one based on our conversation just now before she sleep.

As usual, she says she scares she will hurt my feeling because I'm being too nice to her and this will make her feel bad if she doesn't reciprocate the same feeling.

She also said because of timing and if she didn't experience past bad relationship/breakup, she would have already accepted my protection and pamper.

I told her let's go for a short getaway trip on March and she agreed and went off to bed.

Timing is off and I should wait the right time then. 

Yes she still in touch with her previous ex as a friend according to her. Last night, I chatted with her and she said she knew nothing will happen between them and remain as friend at the same time praise her ex is not bad if he willing to change but she won't demand only observe. I told her the only way to let go is you can't erase memories instead accept the truth and move on. She said already accepted and moving on but sometime will miss her ex.
