My moms best friend died 10 years ago. We had known her since I was small and all of us kids grew up togther. When she died, I felt alot of grief, but what surprised me (in retrospect) was the waves of grief I felt months and years later. Not all the time and every time, but way more than I anticipated. I'd drive by her house and my heart would pound, or someone at work who knew her (we worked in a the same school district, but not the same school) would reminisce about her and I'd well up in tears.
I'm just saying this to say it can take a long time. But, as I am writing this, it doesn't hurt like it used to. I visited her daughter a few months ago and we shared memories, and again, it wasn't painful-it was just nice.
