keep them anyways but hide them

OP here- A couple of points of clarification: 1) She wasn't paying the bills- I was looking for a cheaper apartment. We'd have gone down from a 3-bedroom to a studio. Where I live, I would have been paying a pretty standard rate for what a studio is- it was just convenient to be renting from family, with whom I generally get along. 2) He's my fiancee now. We'd have been married by the time we moved in. 3) She has definitely had some interesting idea manifest over the last couple of years, as she has begun reading the Gospel according to Saint Google. It seems these days she will take any chain e-mail she gets with about the same degree of seriousness as the actual Bible. For most of my life, we have had very normal and respectful boundaries about our differences in belief. I knew she had some odd ideas, but the idea that she would demand to have control over every book, movie, piece of clothing, game, etc. that we had in an apartment we were paying to rent was much further out than I thought she was. 4) When I say she thinks they are demonic, I don't mean she doesn't want me watching Hellboy or other movies that are about demons. What she specifically said is that the physical objects (outlined as movies and books that depicted violence, sex, horror, fantasy, aliens, superheroes, any object that had any cultural reference that could be traced to a non-Christian religion or superstition, satanic heavy metal and video games, etc.) were actually all carrying demonic spirits in a real and physical sense, which would be brought into the apartment with them, and she needed to protect herself by not letting us bring the demons in (the apartment, while having a separate entrance, is attached to her house). So, needless to say, we thanked her very much and cancelled our plans to move into that apartment pretty much immediately. The FML is mostly that she's so far gone from when I was younger, and that she sprung this on us after we told everyone we were taking the apartment, rather than up front when we discussed rent, parking, furniture and pretty much every other detail.

Let me get this straight -- she's O.K. with you and your boyfriend living together, and helping you do so, as long as you don't read, listen to, or play something objectionable??? Seems to me you should tell her her restrictions are fine with you, since they will give you more free time to fornicate.

Sounds like she's a Jehovah's Witness

So it's almost like you're moving back in with your mother...yaayy

Was call of duty on the the list?

Aww man, nothing worse than mothers like that. Had to hide half the music I listened to from my mum when I was younger. Even worse when you're an adult to be sure.

You should post the list :3

Write her a letter declining her offer on the backside of an old Playboy.

How many pages?
