‎"Mummy, there are hundreds of presents under Daddy's tree for {current Fiancé}, why don't we have that many under ours?"
Unreal. Seriously. What a stupid, impulsive, selfish git. We have bought presents for the kids from both of us together, not separate ones from Mummy and Daddy, and we gave ourselves a budget and discussed what to get them. We have got them 4 decent sized gifts each (plus the contents of their stockings on their bed) but the girls were at his on Thursday, and apparently there is a huge pile of presents for his current infatuation under his tree.
I'm speechless. Could he not have waited until they'd gone before putting this explosion of excess out for all to see? He's always been like this, he expresses his feelings with money. The bigger/more expensive the gift the more it means to him. If he doesn't get a huge pile of fabulous gifts at Christmas or his Birthday he goes off into a massive sulk. Mega childish I know, but he's always been like this, he used to over-whelm me with gifts, and I was forever saying to stop buying so much. Obviously as he's massively loved up right now he's gone off on the deep-end and bought loads of presents for his new Fiancé, and in his excitement he's stacked them up under his tree, not once thinking that the kids would see this and then look at their presents and wonder why he's got so much for her, and so "little" (in comparison) for them.
I gave a politicians answer and, after pointing out that love is not gauged by how much you spend on someone, changed the subject, but in all honesty I want to rip his head off for being so insensitive and thoughtless, and making our girls feel second best. 
Bastard.
