Husband staying out for a week

Me and my husband have been having a lot of issues since our son was born a year ago. It reached a point where we were continuously arguing. He said this is all so overwhelming and wanted to stay outside in the same city in a hotel for a week. He left already. I dont know what to make of this. I honestly feel so much at peace being home without him. But is this the end or is there hope. I dont know what to make of it.
