The begining of the rest of my new life? (3)

[Ripe]

I don’t know what STBXW wants from me now.
She is again visibly melting down in the way she addresses me. She is softer in her tone of voice.
Last Tuesday I went, as usual, to STBXW’s house to pick up the kids. She passed me a paper bag with something wrapped up, saying it was a gift from S7.
At night she called to talk to the kids and asked me if I had opened the gift. I hadn’t, because I had not had the time. Since the kids were already in bed I told STBXW I would open it the following day together with S7.
Wednesday STBXW called me again and again asked me about the present, which I hadn’t opened yet.
Later on I opened it. It was a framed drawing made by S7 during Art Class. I hung it on the wall. I asked S7 who had framed the drawing and he replied the teachers had. I think STBXW did it, not the teachers.
Anyway, I felt some discomfort inside caused by STBXW’s questioning about the present.
Why was she asking about it? What did she care about? More importantly, why does she think I should answer?
For a moment I considered that the question is kids-related and so far we have been getting along pretty well when it comes to the kids, talking about everything they do.
But then I realised this is beyond that.
STBXW is asking about my feelings and emotions. But she is not entitled to them anymore. How I reacted is private, is between me and S7. I don’t feel like sharing my feelings with her anymore.
I am now considering establishing a limit by telling her exactly that, that I have already told S7 what I thought about his gift and have nothing else to say.
The problem is that this might ruin the current good relation between STBXW and me when it comes to the kids. And ultimately this would reflect on the kids.
