I moved in with my gf before we dated and have been living with her coming up on 3 years in June and dating her for 3 years in September. You will need to be able to highly tolerate the people you move in with. Being an OCD person can make things harder on you. Some people moving out for the first time or that are young fresh out of the house don't like to clean up after themselves. My last roommate that lived with us in our house was good friend for about 5 years and we don't speak anymore. Living with someone can definitely change a relationship. But for a 950sq ft apartment here in Decatur was 650 a month at the time. Two bed room, two bath. Electric and cable were seperate, everything else was included. But right now when it's my gf and I splitting the bills we would spend $500-$550 a month including all of the utilities and such. Not including food though. Right now is tough though because my gf lost her job, so I'm the only one in my house with a job, out of 2. LOL But yea, it takes a different kind of responsibility from just waking up on time or something along those lines.
