I am divorced/ separated seven years my son is now 18, we had a very messy separation and divorce, my son and ex moved out when he was only 10, She always made Co parenting very difficult and was in another relationship immediately if not before the breakup, which I found difficult - I was excluded from family events and milestones, Christmas, birthday, Easter etc .. including his confirmation and more recently his 18th birthday party I was 50 in February and I didn't celebrate as I have no family around , - he has now completely stopped taking to me , and doesn't visit or want to make any effort except sending me revolt requests, which he doesn't even say please or thank you for- I feel useless, - , I also lost my job 18 months ago, but I'm ok as I have savings and a house, which is empty besides me and my dog - any advice for a single, depressed Dad
