I've only been the initiator of a break up a couple times. This girl has been nothing but good to me and we had some fantastic times but it's time to move on. We've been married for less than a year (for taxes) with a prenup. Together for shy of 3 years. I'm definitely the best guy she's been with. She knows we're on rocky footing at the moment and is trying to save things. (she's working out more and trying to please me in general)

The particular advice I need is to (1), let her go while minimizing the psychological impact on her and (2) be able to safely help her through this transition. (finding an apartment, moving, etc.
