Why he stopped being jealous?

My fiancé in general is a. Jealous person when it comes to my outfits, even if they are not over. He doesn’t let me share anything too much on social media.. I don’t mind.

I know jealousy is not not healthy. Am not defending jealousy..

But my question is how can a man go from so jealous person to now he’s telling me post whatever you want on social media, and the picture that he asked me to post it was a bit sexy..

How w man can change like this? What changed him? You think he doesn’t care anymore about me?
