<human>: Can you provide a brief overview of the text?

This week, I went on vacation to Hawaii to attend my father's wedding. While on vacation, I received tons of texts from my ex at first saying how lonely she is, and will never get married. These evolved in to questions about my feelings towards her, which then evolved into questions about her desire to reconcile with me. Hesitant and civil at first, I eventually wore down and admitted, yes I do miss her, and reconciliation would be possible. The day I get back from vacation, she begins acting ice cold to me, how we usually are to each other typically. 

This is strange to me, leaves me with many questions. First, was this just a lame attempt to make herself feel better at my expense? She frequently expresses her desire to be married and have a family (with other bro's), was she just trying to make herself feel better about not achieving her goals? Was she simply just trying to interfere with my vacation? Why ask me to get back together, and then basically go back to NC, as it was before? I questioned her about the rapid turnaround, and she advised me she was simply busy at work for the past 3 days (seems BS). She frequently mentioned me buying her a ring and a house if we get back together, which seemed an odd jump from our previous semi-NC status. Side note, I recently have earned a moderate amount of money from my second job, which she knows about.
<bot>: Former SO of 6 years asked for reconciliation after almost 3 years apart, my dumb self agrees, she immediately stops talking to me.
