There is no rule or law that states that couples cannot remain living together during a separation. Spouses may choose to stay under the same roof because they share a family together or because they cannot afford to live alone.  Although, it may be tricky being separated while still trying to live together. It might negate the entire purpose of the separation. If a couple has the means to live apart during this time, that might be the best option. It can provide a much-needed mental and physical escape. Couples should use this time to reflect on the relationship and see how it feels to be apart. Sometimes, that space is necessary.  Depending on how well the two do living apart could determine whether they would like to get back together or move forward with a divorce.
