Background- ExH and I were together 10 years (married 4). We have a 5yo DD who we share care of. We separated just over 3 years ago, and although there were obviously difficult times and ups and downs, the split was amicable and was largely due to us having drifted apart as a couple, being more like friends who lived together (separate bedrooms).
We both now have new partners. ExH lives with his new partner. We are both much happier in our new relationships.
As I said, we are still friendly and will be in touch over arrangements for care of DD as well as other bits and pieces such as have you heard about X mutual friend who had a baby or have you heard the new song by X. I have absolutely no romantic feelings/attraction to him.
This week I sent him a link to a news story about Huntington’s disease, as he used to work with people with Huntington’s. He replied “Oh yes I saw this in the news. X is a bit uncomfortable with us texting about anything other than DD so might have to keep it businesslike from now on. Hope you understand”.
What do you think? I just replied “Ok”.
