I have two DS who I coparent with their father, who sees them twice a month. Their father has a new partner who I get on quite well with, our relationship was rocky at the beginning but I feel that we are pleasant to one another and she seems like a lovely woman who my DS adore, this brings me alot of contentment that they are happy there.
My ex and his new partner have a DD and their birthday falls a few days after mine- this year it falls into the same weekend. This particular weekend is my weekend to have the kids, so I had went ahead and made birthday plans that we could spend together.
My ex's new partner has text my mum, which I am not happy with, to ask if the children could spend that weekend with them instead due to it being their DD's birthday party. My mum AGREED, without my consent, and to be honest I've cried over this. My mum said I am being dramatic. I feel undermined and like my plans and feelings have just been trodded over. I had quite a heated argument with my mum this morning over this and I text my ex's new partner to ask could we come to an agreement over that weekend (half with me half with them), to which she was quite snappy with me. I went on to say it was best to contact me directly regarding arrangements for the kids as my mum doesn't always know what I have planned.
Am I being hormonal or am I right?
