Did you plan for a break up?

For all those couples currently or planning to live together, did you guys talk about what would happen in the unlikely event you break up? If so, how did you broach the topic? How did the conversation go too?

My SO and I are planning to move in together soon, and I’m just wondering about how the logistics would go if we broke up (not that I want that to happen, but with living together I can see how it would complicate things a LOT)
