Most Helpful Guy
Taking into consideration that he has changed into a wonderful man that is so giving in nature now, it feels more like a tactic to win you back than anything else. He is claiming to be a changed man that wants to atone for what he did. That is a classic way of manipulating someone. Even if he is genuine there are a lot of bad people that have used similar tactics. I understand people being worried about you.
As for them thinking they have a right to judge you, well the truth is they do have that right. Just because society says we shouldn't judge someone, doesn't mean we don't have the right. Judging others one way or another is just something humans do. We are all judged based on the decisions we make, even if those decisions don't effect anyone other than ourselves.

I think they're just worried about you. Becoming friends with your abuser is a big risk. Mainly because he could get abusive again, but also because those ties are extremely hard to eliminate once you've been married and in love. Continuing to see him and be friendly with him could cause feelings to linger, whether you realize it or not.
I think they just want to see you functioning independently from him.
