Relationships

What is she feeling and is she toxic?

So I used to like a girl and she knew about it. But she started ghosting me, moved to a different city but still used to text me and tell me that she loves me as a friend and I am important to her. Last month she informed me that she got engaged and then told me that she was seeing someone since last year. I told her that I loved her but didn't want to stay friends anymore since I was kept in the dark about her relationship with the other guy by her. She didn't want to end the friendship but I did because I was hurt that she didn't walk up to me before and told me about her boyfriend. I have been trying to move on for a month now, did not speak with her and have made significant progress but this week she texted me accusing me of not following what I preach (she was replying to an insta story) and then blocked me because I did not respond to her DM.
So girls tell me, what in the world is this behaviour? Isn't this toxic behaviour, where you claim that I am important to you and yet keep me in the dark about things, ghost me, walk back whenever you want, then break my heart, tell me that I shouldn't feel sad and then not give me space to heal, and when I forcibly take my space you throw a cheap shot in a DM and then block me? In my mind it is a toxic behaviour but I need your opinions on this.
