Talking with a model, getting mixed signals - What should I do?

I will preface this by saying that there are some childish and even bizarre aspects to this post. Anyways, I hope I can get some insightful advice because I find WSO -  as ridiculous as this may sound - is the best place to get the cold, hard truth. 

A while back, I began speaking to this foreign girl admittedly way out of my league in terms of both looks (she happens to be a model and not the fake IG types) and money (her parents are insanely wealthy). From the get go, she was showing positive signs directly saying I was her type, cute, and asked if everyone from America is this mature and thoughtful. We spoke everyday for hours with her staying up past midnight consistently just to talk. After some time, however, I sensed she had suddenly grown much colder (almost ignoring me - at least from my viewpoint). I am someone who is prone to immediately "cutting losses quickly." In other words, I genuinely hate pursuing or begging for the attention of those who simply don't care about me. This ultimately led me to essentially cut off this whole thing off and ending it. I had assumed she had blocked me on one of the apps we spoke on and sent her a message testing this out only to see the message go through. The conversation that ensued ended with her saying that she did not care and that it was tiring to speak and that were was no need to continue this. 

I will admit I was a little distraught by this whole thing because I genuinely had never met anyone who had demonstrated the exceptional level of kindness she showed when we first met. Nonetheless, I passively let it go with the days that followed. About two weeks later, I go on that same app and notice she had sent me a message two days prior apologizing and saying that the hurtful things she said before were due to a period of her having some problems. We talked and she unblocked her contact avenues (number and other foreign social media). We begin talking again and she is as enthusiastic as before complimenting me and just overall showing great interest. Yesterday, we talked quite a bit and in the midst of this we ended up discussing why she had messaged me again despite her saying that she did not care about us speaking further. She then asks if I like her and I say yes only for her then say "ok" and "I understand." After this, she has been talking like normal but hasn't seemingly outright accepted or rejected this. What does this mean and what should I do?
