Gabriel- Spend the time that W is away keeping yourself busy. I think you will find that yes you will miss her but at the same time you will enjoy the break. That is how it was with me when H went out of town.
Your W will have lots of time to think and get herself together so to speak. I agree with UD that there probably won't be any major changes right off the bat of her return but it may make a difference if even slight.
