My second son has estranged himself from me after he and his mother (my ex) had a fight several years ago. He and I were starting to rebuild our relationship after his mother and I were divorced. Ive been attempting to contact him but he hasnt answered my emails (I send him several a year) and he doesnt seem to have a very big footprint on the web. Some background: he tried to O.D. on some OTC meds shortly after I moved away to gain employment. He has been diagnosed with Bi-polar disorder. If he told me he never wanted to hear from me again (and why) I would leave him alone. Not sure if he thinks I dont love him or what but when he dropped out-of-comm it left a hole. Suggestions? Anecdotes?
