I was completely broke and in debt when my ex and I split up.
The 2 boys stayed with me. Ex went off to live abroad for 6 (SIX!!!) years. It was very trying financially, extremely trying sometimes (like in winter, do I eat first or pay the heating bill??)
But not one of those difficulties, honestly, not one day in financial distress was as bad as the way I felt in my dead marriage. For years I was broke but happy, and my kids have thrived.
I wish I had had the time and resources to make a perfect plan and transition, but I didn't, and ultimately it all worked out. My only regret is I wish I had left 2 years earlier!
Peace-
B.
