Hi, separation can actually become a beginning of a "better" life. Stress level drop, you stop walking on eggshels, tension between the two of you will drop too, it is a chance to see what you will be missing, it will give you time to process your emotions...
A lot of people here will tell you that separation some times brings more relief than heartbreak.
I think Ellie gave you some good advice, this will be your time to enjoy, work on you and try to become the greener grass. Stay strong, good luck K
