If you are separated from your spouse now, either physically or emotionally, I am so sorry. I was separated for 16 months from my wife at her request, before we reconciled. I know this is probably a time for you with a lot of complex emotions such as fear, anger, sadness, regret.
One helpful illustration I saw in a Divorce Care video was a picture of a music equalizer. During normal marriage our energy ebbs and flows between our physical life, emotional life, and spiritual life, but during a separation or divorce, our energy going into the emotions spikes to the top of the chart.
That may be how you feel now. You may be feeling hopeless also, especially if this is a separation that you don’t want.
I hope you find lots of encouragement at this blog both from parts of our testimony and from other resources.
If you are a Christian, I remind you that the Holy Spirit is your Comforter.
