Oh yes, everything can definitely change and completely.
A few years ago, Yona gave a prediction to my cousin, who was in an on-and-off relationship with his girl, the only one he had been dating for the last couple of years. Yona predicted that they were going to get married soon, and then gave him a bunch of sequences and events regarding that girl, like how they would go shopping for a house and pets. So my cousin was pretty sure that he would end up with her.
But things continued very slowly, so he decided to get another reading with Yona 4 months later. This time, Yona gave him totally different predictions: that he would no longer be with that girl and that he would meet a new woman for a serious relationship. She gave very specific and detailed descriptions of that woman and the circumstances of how they would meet and how confusing it would be initially, and that she wouldn't want to have kids.
It was very confusing for my cousin since he was still interested in his girl and wasn't planning to date around.
But eventually, he ended up engaging with a completely new woman whom he met under completely different circumstances than Yona described. Nothing was ever confusing - they started off very organically and fast. So far, they're happy together and even planning a baby.
So seems like Yona was twice wrong: about getting together with the first girl and about the circumstances of meeting the new woman, since the descriptions didn't match.
It was very sad since I love Yona and believe she is the best reader. But seems like some things still can change, especially love life-related.
I was trying to analyze my cousin's experience. Maybe Yona just couldn't connect with him well, or he had a very strong mind and will... I don't know...
