"Breaks" in relationships?!

So I've been with my SO for a year & 3m and we've been going through kind of a rough patch in our relationship. Constantly arguing, not spending as much time with each other, not letting each other know what's bothering us. It's been really tough, it made me feel unwanted, made him feel like a bad boyfriend. We're just having a rough time. We decided just yesterday after hours of breaking down, arguing, and yelling out our feelings to one another that we need to do something different. We thought about counseling, taking a break, heck we even thought about breaking up but we can't do it. We know we're meant to be we know that we're gonna be okay we just need some alone time. So we ended up deciding on "taking a break." The only problem is we've never been in a situation where we've had a rough time in a relationship but wanted to do everything in our power to make it work. So my question is what is "taking a break?" Is it acting like we don't exist to one another, because I've gonna to another house so we're separate now so we won't be able to see each other. Is it talking as if you friends? I don't really understand it. My whole life I've said if a guy wanted to take a break with me I might as well just leave him because it's the same thing but he's different. He's the one I want to be with. We've agreed our "taking a break" will not include sleeping/talking to other people (appearantly to some that's what it means) because we're trying to work on ourselves to become better for each other. Any advice?
Thank you so much in advance.
