Johnny, Sorry you're here and welcome at the same time.
Give her the space she needs. Cut out the ILYs - it does sound like you've started this - keep it up. No begging, pleading, etc. It'll only push her further away at this time. Be upbeat and positive when you around your W.
Work on getting a life (GAL). Do some things you've always wanted to do but never have. Pick up some old hobbies. Re-connect with old friends. This is for you. It may have the side effect of making you more interesting to your W, but that shouldn't be your focus.
Be the man only a fool would leave.
I would say there is hope for you, but there's also no guarantees.
