He texted me yesterday .... "Is it okay if X stops over if I have the kids at yours?"
Um. No. Actually, no it isn't.
I have no objection to hisgirlfriend, I thing it's great he's finally moved on. I have no objection to her spending time with the kids when he does.
I don't, however, want her in or anywhere near my house.
I suspect this is a not-very-adult solution of the ex's to the fact that his bedroom (his housemate informs me) is squalid, and he'd much rather shag her in my nice clean bed.
Am I being unreasonable?
