I don't think your brother should marry her dude. Simply because you two will have one sad life AND one day it'll be obvious to your brother what happened between the two of you. Truth always comes out. If it comes out of your mouth good, her mouth - better. since she's not sayin and you're actin chicken little- the worst could happen- HE WILL FIND OUT. So go tell him everything. Brothers don't necessarily need to be enemies. She's just another brick in the wall- and she's already loose. Explain that to her. One loose brick can bring down a wall! TT
