I've started my contract (the one with the company my STBXH sometimes works for).
We had a 12 hour journey yesterday to get to our first destination.
A number of the people (quite a few of them) have worked with my STBXH on various projects in the past - a couple of them at the time when things were really falling apart and shortly after.
One of the others, who had worked with him a good few years ago in 2013, mentioned him a couple of times.
Now, by what she said, she very obviously doesn't know what's happened...why he left and with who and she doesn't know about the child. And she very obviously hasn't seen something major has happened in my life by how different I look, whereas every single other person I meet comments on that.
Anyway, I said something very neutral when she brought him up, and stayed totally neutral in myself so that nobody could detect anything from me.
