I have to agree with Christa (and Natasha). As much as we joke about all the things you can do, this could really be a problem in the future. Christa makes a good point, she will be living so close by that this could really be an issue in the future. I'd hate to see her make your entire life miserable, just because of how she is - so the sooner you can get some rules and boundaries in place, the better. I know it can't be easy, for you or for Cain, but I do think the sooner you two deal with this the better it will be, for everyone!
