Have you shared your feelings about this with her? If not, I wouldn't. To me this shows how much she really loves you. She came back to you, her love, her husband. I would take this as a sign that she is rewarding her loving cuckold and that no matter who her bf is, she married you, her cuckold, and yes her man. While you relish is being denied, don't forget about what she might be feeling and that she will at some point need to feel her husband. Also don't forget that this was her choice, and as her cuckold you should feel rewarded.

Sounds like you have a great wife, and thanks for sharing your story.
