Ray the bad memories do fad with time. The good memories will come to the fore front. It all takes time. People asked me how I coped with it when my wife passed and I told them one day at a time. I found certain things would trigger emotions and make me tear up and tug at my heart strings. After awhile I realized that the emotions were normal and that it was your minds way of telling you that you had a strong connection with this person. If it didn't affect you, you wouldn't be emotional.
My prayers are with you.
All my best, Stephen
