Of course there is hope. Hope you can discover the life-changes you need to make for you, not for her and not with the idea she will "see the light" and come running back.
This time is about you, time for you to discover and rediscover yourself and life.
This is an impossible situation and many people will offer all kinds of conflicting advice, but honestly have no idea what you are going through.
Also, understand she is not going to be making any moves toward you or the R; there is something else drawing her and she is going to reflect you and the marriage in the worst light possible.
Also understand (and this is the impossible part), this has nothing to do with you. These were decisions a long time coming without you.
Do not chase or pursue, unless you want to guarantee the results.
Turn all the anger and sadness and bitterness and disappoinment inside and focus on you because you are the only one you have control.
