Dear bobB~
I read elsewhere that after six months you were still devastated by grief, and that is seemed to come in waves.
Six months is not a long time, and in fact there is no timetable for loss. Everyone is different, plus of course it depends on how close you were. Some people, myself included, form half of a whole -a true partnership where two people face life together. Sadly if one passes away the other is - or so it seems - only half compete.
No doubt everyone has told you that things get better in time, which is true, even if it does not seem like it now. For me it was having another to fill my life, in the meantime until we found each other distraction was the best I could do, work -and lots of it - plus family.
All I can suggest is to try to fill your life, even with things you might not have considered before, from joining a gym to a book club.
If you are lucky, like I was then you will meet someone else, if not then those activities will help heal the hole in your soul. Meeting someone else does not denigrate what you both had, in fact it confirms it.
