Hi missmy, Yes, that is worse than losing your "love", losing your best friend. I miss that way more than the romantic part, which I think is one of the reasons that when others say "You will find someone new", it doesn't really mean much to me.
Yes, although you have been at this much longer than me, I have trouble making new memories without the old intruding. I find myself thinking how much my W would have enjoyed this or how she would have reacted to that. I can't tell you how to stop this or if it will last forever but I know you aren't alone. This is especially true when it comes to things that my D's are part of.
