I do get that they needed time to settle their thoughts but you don't move out of nowhere and leave a note saying: it's better to take some time. That's what buffles me. If you didn't want to end the relationship in the first place, you could just go to a hotel to take some time like the other comment said. The action of getting another space and taking all of his things seems a little extreme to me. It literally seemed like he wanted to break up so I was surprised that he actually wanted to be together after moving out.
Maybe getting a place of his own wouldn't have been so bad if he actually took the time to explain instead of expecting that a letter would be enough.

i don't really get how garam came to the conclusion that literally running away without any explanation but a simple letter was going to make their relationship better. I'm still flabbergasted about that.
