Ex-h and I separated 4 years ago. We have 3 DC, 13, 9 and 7.
He lived close by until a year ago when he moved to be with his pregnant girlfriend 4 hours drive away.
While he was here we had almost 50/50 shared care, he was very close to dc, they adore him.
He now sees them eow (every other weekend). Picks them up either Friday or Saturday drives to his house then brings them home Sunday.
He can be difficult to communicate with, often not responding. He has never not turned up to see dc though.
So ds's best friends bday party is on Friday. I contacted ex over a week ago to tell him and ask whether he wanted to collect them Friday or could ds go to the party. He never replied so I told ds and the mother that he could attend.
I contacted ex yesterday to remind him and he said his baby is having their bday party on the Saturday so he needs to collect dc Friday or not at all....
This is not the first time things like this have happened and it pisses me off that dc are caught in the middle, having to choose between their dad and plans they've already made. His line is always 'oh well I'm sure they'd rather see me...'
