A girl Ive dated and fucked multiple times started to criticize me on our last date and was saying she cant be with me in a LTR.

One example: why did you go to court with your ex, what if we divorce in the future and you fight against me in court...

I reacted by saying she is overreacting and that she did not know enough about my life to judge me and tried to defend myself. She refused to hug, kiss or have sex that night but we had sex in the morning the day after. In the evening she said she has no feelings and then blocked me on phone and social media. We have not had any contact since then.

Did she have any feelings to begin with, and was it her fear of commitment that made her criticizing me?

Was this a last shit test?

What would have been a better reaction from my side?
