Message today from ex can I swap a weekend as he is 'busy' ( read going somewhere with gf/ow)
Now normally wouldn't mind swapping but it's the weekend 2days after sons birthday and I'd planned to have his party then .
Now if he was planning something special for the kids I would possibly consider changing it. I have said I will have them extra for his w/end and as its half term he will see them extra then anyway. He has changed weekends several times since split ( when visiting ow and I have always had them then) but when I have asked for a tiny bit of flexibility complains and I get a torrent of aggressive emails from him.
But is it wrong and could be seen as denying him access? If I offer him 2 days extra over half term or another weekend swap would this be better( I have said he's welcome to come on sons birthday which is midweek)
