Thank you luvless. No there is no other man. This is one thing she has always said since the beginning that we are we and no room for 3.
How do you know? Have you checked?
Going by what she SAYS won't work, because ALL CHEATERS LIE -- PERIOD.
You would be wise to check this out independently. If nothing else, you'll have some peace-of-mind, but there almost always IS someone else, especially for women. Saying she doesn't want to work at it is a HUGE red flag.
