FS is this a security camera that he has? If he isn't in the home why does he have access still?
Also I wouldn't lie about the anti-smoking class. Just don't tell him about it, he doesn't want to be in the MR then its none of his business.
The camera line is part of a package that he pays for. I cannot disable it fully without having to change our utility bill. He will not change the utility bill. I have tried to get him to cancel and put in my name but he won't. I think he called me "ridiculous". I don't worry about it too much. I turn it off when I want to. He turns it back on. Neither of us mentions it though (he did last time but thought it was because his subscription ran out).
I wouldn't normally bother telling him what I am doing but the course was on a day that I was supposed to have the girls so had to make something up.
