The sexual attraction is something we can not underestimate. I'm glad on some levels that my W moved out so I don't have to see her everyday. Specially if you go from active to zero overnight. Ouch.
Your dream can still be a reality just tweak it a bit. You have two great sons that represent the core of your family. From there you have three options; being a strong single dad, having a healthy reborn W, or finding a more suitable partner. You're not giving up your just taking some of the pressure off yourself and your M.
Anger is not necessarily something you can set aside as it has a tendency to jump back in at the worst times. You have some time on your hands. Work on that aspect of your life. Attack it head on until you can come to piece with it. Read about anger, were it comes from and how to get through it.
