.... I agree with bootyz, she probably feels bad. Lots of people have a HARD time wrapping their minds around the idea that a husband can be ok with his wife fucking other guys.
Unfortunately now you have said you lied and it would be difficult to go back again or she will think your lieing again. Wow... it sounds to me like she felt like she was missing something between the two of you. If you want to keep her, I think for now you need to work extra hard on the two of you. Find out what she is missing, maybe it is just the time apart, but from the way you put it, it doesn't sound to me that she will be ok or want a cuckold relationship at least right now.
Really sad man. I hope you guys can work it out. I admire you two for serving our country, its too bad its putting such strains on your marriage.
