He decided to leave for a few days

My boyfriend and I have been together for 2 years and we have a condo together we have been going through a lot and it's gotten so bad we decided he should go stay with his mom.fir a week or so so that we have some space and we can figure out what we want and if we can learn to appreciate the relationship we have or go our separate ways . Has doing this ever worked for aosmeones relationship ?
