Hi,
my ex and I recently split after 15 years and 1 child. It wasn’t working and we split amicably.
He has met someone new -which is fine I want him to be happy. His new gf has children too.
He wants to take our child on holiday with the new woman and her kids. I said no purely on the basis of my son has never meeting this woman before or her kids and it’s a new relationship (5 weeks) I don’t want him getting attached if it doesn’t work out.
He said I was being unfair.
Am I being unreasonable??
