Need help with Lae'zel romance

Hello!

I've searched the internet for a bit but didn't find the answer to my problem. I'm romancing Lae'zel for the first time, I'm currently on my 4th playthrough. When we arrived to act 3, I spoke to her, and she suddenly said that I grew cold and it seemed like she "broke up" with me. I don't know if I missed anything, but she has 100 approval and everything went normal, she is in my party all the time, I didn't try to romance anyone else. Is this the end of the story or a part of it? I didn't check any romance guides, because I don't like spoilers, so idk what to do. I played with her for the first time ever and found a hidden gem tbh, so I am worried I did something wrong somewhere in act 2
