I don't think I'm being unreasonable here but it's always good to check what others think!
DS7 stayed at his Dad's the weekend just gone. His birthday is tomorrow. His half brother's birthday was yesterday, and he was 5.
On the weekend he was at his Dad's, my ex and his partner threw a birthday party for his younger brother, with presents, food, birthday cake, some of his friends and all the extended family (on that side) went.
DS7 came home very upset because despite his birthday being only 3 days after his brother's, it wasn't acknowledged at all. No presents, birthday cake, no one there to see him.
He now won't be seeing his Dad for 3 weeks as he couldn't have him his regular weekend as he's going away.
Surely that's an awful thing to do, or am I just being overprotective here? Me and my ex don't get along so I'm hoping that isn't clouding my judgement!
