Cory I was in your shoes 6 months ago and can relate to everything you describe. As the others have suggested, keep your head held high, and act like the most confident man in the world. You can go home and cry your eyes out but don't shy away from the conversation in the moment. My EW and I have been D'd since April and I can tell you it does get better with time. It is not the end of the world!
Maybe your W comes back and maybe she doesn't. Maybe you end up moving on and find someone else that blows your socks off. Just keep moving forward and what will be will be.
