It's a big move, and you are anything but gutless. 13 years ago you made an absolutely courageous move to assure a good life for your son. Do it in small steps: write him, call him, and when the time is right somewhere in the future (no time limit on this) see him. Good luck in this journey. I regard you as courageous. You have already shown that you are the kind of person who does "the Right Thing." I salute you.
