The OM is doing your work for you with your W. Already there are problems and that is in the 'honeymoon' stage of thr R. I say again that you need to work on you. R with OM will not last but whether or not your W comes back to you depends on your behaviour. Make her miss you. Show what a 'rock' you are compared to OM. Do not let your W walk all over you and your feelings otherwise she may do this to you again in the future.
Surely you can see by now that what I have been saying about OM is happening. I know you want it all to stop NOW and go back to how it was but obviously there was a problem with how it was before or this would never have happened.
Make it so that when your wife ends it with OM she will want to come back to you. Be there, be supportive etc. but make sure she appreciates what you have to offer. Do not be there all the time. Make her ask for what she needs - say no sometimes if you want.
