Why did she only unblock me Instagram and nothing else?

So I met a girl online and we talked for a year. We both wanted to meet and on the one year mark she went ghost on me for 2 months. When I found out she was dating someone else I confronted her about it and she blocked me on every social media. And then like 2 weeks ago she only unblocked me on Instagram but hasn’t said anything yet or followed me on there. What does that mean?
