Spoke to ex tonight. There is a looooong back story of him being useless and doing less than minimum re our 2 dc.
He is remarried with dsd the same age as our dd (10) and a little boy of 2.
The difference in treatment of the dc is huge.
He told me tonight that they have got his dsd 1D tickets for christmas and our own dd a bike helmet. Dd is a huge 1D fan. She would have loved to go with her stepmum and sister to the concert. Or if they didn't want that they could have told me and I'd have paid for my own ticket and they got dd hers and I'd have taken her.
I know it seems petty to be upset but I'm a stepmum too and try to be as inclusive and fair as I can be when it comes to big things like this and it just feels like the last in a long line of the dc being treated like visiting cousins rather than being with their father and siblings.
