Everything you are feeling is so very normal. There is nothing wrong with you.
Moving forward is so very different from moving on. Moving on would mean that you have given up hope and decided to forgo your marriage and seek comfort elsewhere. Bad move. Moving forward means that you have come to the realization that you can not do anything about your relationship with your W right now and that it is time to walk forward and grow for yourself. As long as there is love in your heart, there is hope.
Try not to look at your W's actions, it is her business and not yours. There is nothing you can do for her but respect her right to chose her path, her way. Again, read Sandi's 37 rules and reread them daily if not more often until they sink in. Pure gold, I tell you, each and every rule. Do not snoop after her (hard as hell, I know), do not interrogate her her, make her think you had an awakening. And a very important point. Have NO expectations. Do not expect a reaction from your W for anything "nice" you try to do for her.
Why would you not want to move forward? I would imagine because you are a creature of habit and moving out of your comfort zone makes you nervous. Don't be. You will soon find out that there is a wonderful wide world of possibilities out there that you never knew existed. Embrace it, go out of your comfort zone, the benefits are multiple.
You have to start to love yourself. If you do not love yourself, how can anyone else love you?
And to return to your first point. Yes, there is not a damn thing you can do about your situation, but there is a whole lot you can do for yourself and that is the right way, the only way. Go out, go to your happy place, go hiking, go to your friends.
