@peace7 - here it is: Husband said he wants to split up and I’ve been totally blindsided | Mumsnet. @mummy917 I hope you are able to keep your resolve; you have done so well and are worth much more than this spineless cretin.
I am sorry your holiday is not quite as you'd hoped and that your 4 year old is being a bit challenging. It won't always be like this.
Forgive me if this sounds a bit patronising - how about doing something on holiday that you would never normally do? Maybe something a little bit out of your comfort zone that you and the children could do together and where your parents could sit and watch with the smallest ones? Something like mini go-karting, where you could have a go as well?
I've just come back from holiday in Devon - it was too hot to do anything, so the dog and I sat beside a river with a book. There was a lovely family splashing about nearby and I was talking to them. They'd had a "day of random choices" in which the little girl had chosen pony trekking and her younger brother had chosen go-karting. The parent had got stuck in and done both with the children, completely out of their comfort zone, but they'd loved it, and said that it was one of the best days they'd had, with lots of laughter and the shared newness of the activities bringing enjoyment beyond screens and frayed tempers.
It doesn't need to be anything expensive. If you're at a beach or countryside site, maybe get your parents to draw up a "treasure hunt" of things you might find there (a yellow shell, a purple flower, a nut shell, etc) and see who can find them all first?
Sorry if these ideas sound sh~te. I just have found that, if I take the plunge and do something I wouldn't normally try, it can bring unexpected joys.
Stick with the holiday, even though it's not great at the moment. It's much better to look back and think "I really hated all that" rather than "I really wish I hadn't left early". It won't always be like this. xx
