yeah i would suggest as stated before...
find a co-worker of hers that looks the best and just start asking her questions about her..
whats her name?, how old is she? is she seeing someone?...
and when she asks you why you want too kno...tell her "the same reason you want too know about dood."
And if it turns out he was boinking her or they had something goin....
dont get mad....
the worst thing u can do to a beezy who has jus cheated on you is too make her feel like u dont care... just say..
"its koo, ill find another, yall are a dime a dozen." and say no more... if u make her feel like u didnt care about her im sure it will strike a cord. let us kno what happend mayne..
