This week, I'm talking about that big step in a relationship: moving in.

A Chicagoan wrote in to Sex & Moxie about her move-in horror story -- relationship was great, she moved in, he started acting cold and distant, she made up a secret identity online and started talking to him about his relationship with her, they broke up. (Yeah, that middle part threw me for a loop, too.):

After living together, however, I noticed a change in his behavior.  It became cool, aloof, overly critical.  I reacted as any normal woman would, "What did I do wrong?"  I began to overanalyze every little thing I did.  We began to argue more and more, even though I was trying to "fix" things. I asked him what was wrong?  I gave him his space, encouraged him to go out with his buddies.  All I asked for was to be treated like he gave a damn.  I felt he had changed, he had said he wasn't sure he could handle my personality and habits now we were together 24/7 and he saw "how I lived."

But that's one of the points of moving in, right? To test out the waters. To see if you can handle being in each others' space all the time, dealing with their dirty clothes slung all over the place, sharing household chores and realizing that, when your lovely angel is at home in their element, they don't chew food like a regular person -- they're loud and smacky and gross; THEY CHEW LIKE A COW.

For some people, moving in isn't a huge step. I've met one couple who moved in together after only a few months of dating. And while I typically am a steadfast you-have-your-space-I-have-my-space person, I did make the crazy leap of dating my roommate. (Rules are made to be broken, right?) What's your moving-in experience? What's your position on moving in?
