Sorry to slam you on the gifts, I understand the thought, but it just seemed like going a little overboard w/emailing her on the rose. I'm a sucker for giving gifts also, I still want to buy ex a cycle magazine every time I go to the book store! I haven't done that lately, but if I slip and buy one, it goes in the closet for now!
Letting go is hard. But look at it from a different perspective: you are letting go of the old R. The one where she doesn't want to be w/you. Then work on a new you. The steps of letting her make contact, ignoring to build curiosity and getting your stuff back will help. Don't necessarily think of this as a LR, but as a need to pull yourself back together. Put your heart into GAL. Eventually it will feel right.
And yes, the w/e are difficult. Start making plans for the upcoming one! It's labor day, so there must be s/t to do to keep from focussing on her.
