Good Luck! - I've been the "Other Woman" by: Anonymous
I've been the "Other Woman" 4 times in my life so far, and I think he's cheating. I'm sorry to tell you that, but you probably knew in your heart.
All you have to do is sit him down, look him in the eye, and ask him flat-out if he is cheating. And if he says no, you'll know if he is telling the truth or not.
Then you have to decide where to go from there.
Good Luck!
