Three words sweetheart... MEN ARE IDIOTS!! (please, any men don't take offense to that, it is a stereotype I know)
Men tend to bottle up emotion in the first place... do your CBT with me? humor me

A-Recieving the email B-This memory obviously doesn't mean anything to him/he can't remember C-(crying?)

now let's change B..... he could have remembered, but didn't know how to console you. He may also not want to admit that he may have felt moved by that song (because he's a man... grrrr, growl at the men ... again sorry for stereotyping)

I know it's upset you hunny and to be honest I'd probably do the same thing... but from words you've told me... try and hold on to those good memories, but put them in there place

now... do I get to poke you until we see a smile?

Take care,
Molly
