In college I lived with my college best friend, and it was a disaster, because we were as different as can be, but the same degree of stubborn. I then lived with an acquaintance-- all business, and I hated it. I missed feeling like I had a “home” instead of a place to sleep.
Then I moved to California. I have lived, in the past 5 years, with all but two of the member of my close friend group.
My BFF and shared and apartment, and then a rented house, and then an owned house (hers). It’s been nothing but good, but we are highly compatible, and have similar attitudes about everything from cleaning to sleep schedules to activities to which way the toilet paper goes (in that neither of us cares). We’d cook & eat dinner together nearly every day, share laundry, clothes, books, movies, purchases, etc. We functioned a lot like a family, and I’ve really loved it. There’s never been any “labeled milk” in our fridge.
Two years ago, after moving into our current house, a third friend moved in (Call him Roomie 1). What he did was have a “trial” month to see if he’d fit in. And he did, so we had a 3 person faux-family.
A couple month after he moved in, another friend (Roomie 2) had a run of bad luck and we offered him our couch in our den. He did not mesh with the living style of the rest of us. He was far messier, kept crazy hours, and was just. . . not compatible. All little petty stuff, like holding loud conversations with people who were trying to read (you know how non-readers seem to want to “rescue you” from your book?), leaving bottle caps in the sink, turning the thermostat too high/low, not cleaning the toilet (generally not being careful with the house, bad idea when you live with your landlord). He wanted labeled milk. He felt like just some dude renting a room, which I think made us more intolerant of his petty annoyances than we were of each others. It’s easier to tolerate people when everyone is invested in making the relationships and living environments work.
Him, we had to evict.
Roomie 1 eventually got his own place, because he wanted more space and to be closer to work. We were all a little sad when he moved out.
This summer another good friend, Roomie 3, moved into Roomie 1’s old room. So far it’s been absolutely fabulous, no bumps at all. I’m getting married in the spring and moving out, and I can only hope living with my fiance goes as well as living with my BFF and other friends have. I’m going to be bit sad to go-- we have a wonderful, genuine “home” here. It’s been the best thing that’s ever happened to me.
It doesn’t have to be bad-- but it depends a lot on how compatible you and your friend are, and how much compromise you’re both willing to make.
