What a dirty #*&!!!!

So I just found out on Snapchat that my brothers long distance gf is messing behind his back with my husband's brother. And also she has been a long time friend of mine. I'm so in shock that she would do such a thing and furious!!! My brother is away working his ass off and she goes and pull a stunt. All I can say is what a dam hoe she is. 😱 My brother deserves better than some two timing fast fix
