My husband released my mobile phone password and put me out of the blacklist. What does that mean?

I don't know what happened between you, so I dare not comment, but one thing is almost certain, that is, his attitude towards you is better than before. I think there are two possibilities for his action. One is that he has completely let go of his feelings for you, and you can't hurt his feelings. Another possibility is that he forgave you and let you go, so you can keep in touch with him. I don't know if I'm right, but my personal opinion is for reference only.
