Get over it and move on

If you are the person that says this to someone who is trying to get over a long relationship or divorce how do you expect a person to just get over it?

If you are a person who hears this how does it make you feel?

I often take people post let it go and I think wow it’s so easy to say but in my reality it’s not so easy to do. I’m so jealous of women and men that can just get over things quickly.
