I cant help you with any of the emotional stuff - I'm on my own rollercoaster and it sucks!
But I did want to tell you that I packed up all H's stuff months ago, and it was really good! Fresh start. I made my house friendly to date other men, and I didn't want to keep coming across stuff that I thought of as being his. I did cry - but it was nowhere near as bad as I though once I started. And I packed up all wedding stuff, into one box and gave it to my parents, so if I ever need it I can have it, but if not I never need to think of it again.
Thinking of you, and wishing there was an easy solution for H's that cant get their SH*T together!
