Hi everyone, thanks for the thoughts and advice. I appreciate it.
More of a journal entry than anything else, a few tough days since I wrote the first message. WAW is with her family, a bachelorette party for her cousin in Charlottesville. She's texted me twice and emailed once over the past two days, both her initiating contact, with me being friendly but very much "clerk in a store".
As far as GAL, last two nights have been spent with friends, watching the NHL and then NBA, just shooting the breeze. It's nice that I've got a good support network to work with. I've also been going to the gym very regularly (~4-5/times a week), including twice with a trainer. I'm 6'5" and about 210 with average body fat, want to get back to my fitness as I used to run track at the collegiate level. My goal isn't to be strong in terms of buff, but lean, swimmer-style strength. I mix that in with a softball and flag football team through work, and pick up tennis as the mood strikes me.
On the topic of my mood, it's been tough. This weekend I plan to get a box and put all of our wedding photos, different bits of memorabilia hanging on the wall, etc. away for the time being. Definitely feeling very lonely, definitely mourning the situation. Privately, of course, and with my IC. I don't doubt that she knows how I feel, so I've been playing it aloof and cool around her. If we interact, it's pleasant, friendly.
WAW did indeed sign a lease, she'll be ten minutes away, one neighborhood over from where we live in NYC. Moves out in about two weeks, boxes piling up in our second bedroom. We have many mutual friends, a few of which have been proactive in telling me that she's been telling them - she's upset, and genuinely confused and unsure if there's a way forward. I know, I know - believe none of what she says.
Plan remains the same. Live my best life, let her contact me, be the most attractive person I can be, and give her the space that she needs. No pressure. I'm back and forth on whether continuing MC is a good idea; I understand the perspectives on here, but I'm also wary of the downside risk of it appearing like I'm giving up.
