How do you see my ex wife's reaction?

I was 46 and my ex was 44. I divorced my wife last year because I confessed  I have a thing for young men and she couldn't handle it which I accepted. There wasn't much love in our marriage anyways, we didn't have a happy marriage, so we just agreed to move on.

A few months after our divorce, I met and started a friends with benefits relationship with a 20 year old man. When I visited a local supermarket where my ex worked, she suddenly started to yell at me, asking me if I left her for a young man to which I replied no. She told me I should be ashamed of myself and that I am a scum and a creep. I told her it's none of her business, and just left the store and never been back out of embarrassment. 

I never spoke to her again either. She left to work overseas and I am over it, but I don't think she had any right to do that. I am just wondering how other people see it. My friends said she was jealous.

You didn't have a happy marriage, so this was just more of the same
