Most Helpful Girl
Relationship problems are meant to be worked on together - not separate. If you need to be apart to figure things out she's not the girl for you anyway.
If things were going badly I could see a week break showing you that the grass is greener on the other side - things are better NOT in the relationship.
The love didn't disappear in a week, it was likely her will to fight for it, especially since you decided being apart would be better.2
