To all. I sent the message yesterday (Australian time) "I miss you so much W". Simple, short, but needed to do it.
I'm curious why you felt you needed to do that, was it so that you can reassure yourself that your W doesn't care about you and it will help you move on? I'm sure you've read enough stuff around here to know you weren't going to get a fond response from your W telling you that she misses you too and inviting you out for a nice heartfelt relationship discussion over dinner
