Do you ever share your accomplishments with an ex-spouse?

I painted something I was really happy with today and have posted it on FB and sent it to my kids. On an impulse, I also texted a photo of it to my Ex. He called in response and we had a few minutes chat on the phone. (I was out walking at the time.) I feel so ambivalent about contact with him. Even though it wasn’t a bitter divorce, it caused me a lot of pain and I can’t always decide how I want to relate to him.

Not really looking for advice – I’ll cope; just some sharing.
