Hmmm -
I can only speak from my personal experience - the one I had with my now husband of 20 years.
Just like you I was going through some old items that I had forgotten that I even had and my b/f saw a few pictures and an ID bracelet that I had of my last b/f before him - - - my last b/f had died in a motorcycle accident just three months before I meet my new b/f - - - and any ways he was very upset to say the least and asked me to get rid of all the items..... I held out until we were married and then I removed the items from my life, for I had started a new chapter within my life.
BTW - I do still have the articles posted in the newspaper of my old b/f death and I have kept his funeral pamphlet and MY HUSBAND is ok with that.... as I keep all these type of things of any one that dies that I once cared for.
LoVe,
Rhapsody - ((( hugs )))
