Ex going through my bathroom bin!

[MoonshineWashingLine]

Ex comes to collect dd from my house a couple of times a week. Every single time he says he needs to use the loo and I've noticed a few times now that the rubbish in the bathroom bin has been dishevelled after he's been in there.
He was verbally and emotionally abusive when we were together and things were hard after the break up but recently I thought things were improving. Mostly due to the fact that he's seeing some other poor women, who he has told me was in an abusive relationship herself prior to seeing my ex, so I assumed he had detached from me and moved on to her...
However he still tries to pry in to my personal life occasionally under the guise of pretending to be concerned about me or something (ie. 'Oh why are you going to the doctors? I hope you're ok.' Etc etc) and now I am fairly certain he's been checking out my bathroom rubbish!
I'm not sure whether to approach him about it via text... he will no doubt deny it but I'm of a mind to say if he can't respect my privacy he's not coming in the house.
I actually move in a weeks time so I'm wondering if he will be like that in my new house... I still live in the house we shared at the moment.
He also asked for my new address today (in a text) and he said 'if you want me to know where you live that is' which I found really odd. I didn't think anything about giving him my new address until he said that (and niw the bin incidents!) So I haven't actually given it to him yet...
Feels like just as I start to think things are improving he goes and does something idiotic again!!

When he said he didn't know what he had done you should have asked him why he thought he had the right to use YOUR bathroom, or else told him you know what a nosey twat he has been and he is not ever using your facilities again.

Hold it in.
