I've thought all of this type of stuff too - but please don't ever tell your W about these thoughts otherwise you're back to square one. You might feel wronged but so does she. She's expressing her feelings about them. I don't think you should - that would be making excuses. You've got to man-up and take responsibility. Part of that process is not to make excuses.
Ignore the messages she's giving out about finding someone else. Same happened to me - W telling me how there were loads of men buying her drinks, walking her home etc etc. I see it as my W re-establishing herself as an attractive woman in control and able to make choices rather than the woman my actions had turned her into. I'm pretty sure this has just been talk - and the thing is, if those opportunities are available and your W chooses not to take advantage of them them thats a great choice from your perspective. You've got to roll with the Thurs sitch and let your W make her own choices. IMO show her max trust and who knows, she may repay you.
