Why did my ex keep contacting me before suddenly blocking me?

We had a great 4-5 year relationship. But this relationship started as temp one because we knew we had lots of differences in religion and culture. Before we could blink we were in crazy love. years 4-5 weren't good because she felt like there was no point in continuing. but we didn't want to break up. But over 4 years you learn a lot about people. I was ok without her after many issues. She called me mean stuff lots of times and I just ignored it. But one last call was when we were suppose to be intimate and she called it off because she was emotional about it, she said I was the reason for her misery. I put 4-5 years of nothing but pure love, even when she was finding reasons to be upset, some people love misery. Although she called back an hour later and apologized.

I wanted to give her what she asked, her space and break up. 3 months later on her birthday I messaged her and wished her well. Couple months later she did the same. Then she contacted me again over the year 3-4 times.

Last month she messaged me on Instagram and said we should hang out and have a coffee. I agreed because I wanted to end it on a good note, as we've so many inside jokes, memories and feelings. She was on vacation with her family and it was her birthday. I wished her well and she liked it and thanked me. A week later I get on instagram and her profile pic wasn't' there.

we usually use whatsapp, but because my whatsapp wasn't working for couple of months. She used instagram. I got my whatsapp back a month after the convo on instagram. I messaged her on whatsapp. She saw my messages and didn't reply. 2 hours later, her profile and status disappeared. Clearly blocked. Until this I was doing fine, but after the blocks, I am falling for her, her game is working. I am not obsessive but I do appreciate clear communication. I feel her family is behind this if her mood changed on vacation. If she was seeing someone she wouldn't message me and send hearts a month prior to blocking me.
