Hi. I'm having a dilemma, and don't know what top do for the best so I'm turning to the wisdom of mumsnet 
It's my sil to be's hen weekend on a couple of weeks. I'm her chief bridesmaid, and organised the weekend so really don't want to miss it. When we first booked it I was with my now ex, so naturally he was going to have our boys at my house (we weren't living together). Since then we have split up, but he had said he can only have the boys if he has them at my house. I don't really feel comfortable with this, and my Mum says I should point blank say no, but if he doesn't have them here I don't know where he would have them.
He lives with his dad, who is a miserable sod, and the boys aren't allowed to stay there. My mums suggestion is that he takes them camping, but he list his job recently so probably can't afford it.
Does anyone have any suggestions?
