Not to state the obvious, but boundary setting is a hallmark of any healthy relationship. But this practice becomes especially important once you make the decision to move in together. Cohabiting can bring up all kinds of discrepancies: one partner may need more alone time than another, or one may feel a little more comfortable leaving the bathroom door open while the other feels awkward about it. These disconnects are totally normal. By setting boundaries before you get comfortable in your new home, you can ensure that you’re respecting each other as roommates.
