You’d steal a friend’s guy
This is one of the lowest things you can do. Whether you’re stealing a guy right out from under a friend’s nose, or dating one of your friend’s exes, it takes a certain delusional quality to believe this is ever worth it. If you’re willing to steal a friend’s man, which inevitably will lead to the death of not only your friendship with that friend but all the others that take her side, then you are buying into the fantasy that this one person will fill the void that all those friends left. And that thinking belies a host of other issues.
