Morning all. Had a fairly trivial but annoying situation with my ex husband this morning. Long story, but he regularly sees our children round my place, as it's better/easier for them, as he lives further away. I'm not particularly happy about it, but will live with it until we divorce later in the year, and can formalise other access arrangements.
Anyway, children and I recently got THE most gorgeous pup. He's lovely, but like most pups do, will do the odd pee on the floor. I have now taken away his puppy pads (his use of them was hit or miss anyway!), and am taking him outdoors to do his business.
This morning when ex was round, he did a pee on the floor even after being taken out by myself. Ex husband waited until I was back in the room, and pointed out the pee, for me to clean up. He says every time 'your dog has peed'. Then he asked (sarcastically no doubt) when he was going to be housetrained.
I replied that I wasn't his only owner (although I do the bulk of it all of course
, and that the children are able to clean up after him too. Our 14 year old is very good but was out at the time, and he seemed shocked that I would ask our 9 year old to clean it up 
Am I being unreasonable in thinking that if ex is round our place, it wouldn't kill him to muck in and grab a piece of kitchen roll himself?
To be fair, he made it clear from the outset that he didn't want anything to do with our dog (walking him, looking after him, etc). This is absolutely fair enough, but the situation of him smugly pointing out the pee and not doing anything about it, is winding me up.
AIBU? Thanks.
