She also asked me to go shop a bit at a particular store, with her and S. My plan was to go shopping alone once she picked him up, turns out she was planning to go to the exactly same store.

Well, I went with them. Don't know if I should have though. It was ok, we talked, laughed and smiled a bit, but otherwise it's more of the same. She asked me to go to another shop with them, but I declined and went on my errands.

It's been several weeks since she even stayed more than a couple of minutes, and now we are back were she wants to do things again. A bit sick of it.

Together for 8,5 years.
