You haven't Grieved fully until you can Think of them and Smile....
..or even laugh at shared memories
@Suki813
I'd Normally suggest find a Quiet time....but I'm not sure you do quiet time...
...so find the quietest time you have...
Usually have a couple of drinks to loosen up...or a good smoke...
..so get as chilled as you can...and Write him a Letter....
Tell him everything he meant to you...how much you Loved him..update him on the kids..the new house...everything you would have said if he was still here.
Expect to get upset....but that is part of the process.
Repeat as often an necessary.
Pick a day..xmas..his birthday...something Special to him....and repeat yearly if you need to...
