Expectations of what you think life should be when they return should be completely tossed out the window. Life as you knew it w/your spouse at home is going to very, very different for about 8-18 months. This is going to be the hardest thing you've ever done and your patience is going to wear thin, you will need to learn to bite your tongue and not go off on a tangent when they don't do or say what you think they should
The old Marriage is DEAD.
You can not keep living in the hopes that you are rekindling your love and will resume right where you left off.
It isn't that way at all.
This is a brand new relationship with some familiarity.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
