Not sure where to start

Recently separated after 10 yr marriage. We both “outgrew” each other and got too involved in our careers. We have yr old daughter. Its been 4 months since I moved out. But basically we were mentally done a year ago, slept in seperate beds,she sleeps with my daughter to help her sleep through the night. We had a handful of intimate moments prior to the split and Inalways voiced the need for it.

Now we are still ok good talking terms but have both met potentil partners of our own. We both understand we can no longer communicate as “friends” as we feel knowing we are potentially intimate with otherpeople could hurt us. So we have resorted to texting on need-to basis concerning our daughter only. I do still love her and I believe she does too. But i am really investing into someone else whom I feel could go far.

Question is has anyone been in the same situation and is it bad idea to fill each other in on our new relationships? Or are we just subtly teasing each other with this new”high”
