Oh dear Jaffacake2 - this sounds like a very raw time and as though it has only happened relatively recently. I read a wonderful phrase in a family court recommendation by a solicitor recently (a couple who have dragged each other, and the children, though the courts over access following their marital breakdown) which spoke about the need for the children to feel as though they are being ‘richly shared rather than deeply divided’. Your daughter and son in law need to focus on the children’s enduring need for love, security and consistency and, even though their marriage has clearly broken down, to negotiate as adults and parents over their children’s future wellbeing. It sounds as though you have had experience yourself of being a single parent and am, I’m sure, a treasure for your daughter. Although it must be dreadful to see your daughter hurting so much, try not to get bitter over your son in law’s abandonment of her. In a strange way if it was going to happen, it’s almost better that this has happened whilst the children are still quite little as they will adjust more quickly to Mum and Dad being apart. Enjoy your Grandchildren, let your daughter know how much you love her (I’m sure you do..) and do make sure you have some support, and time, for yourself in all this.
