This is true. Don't let your emotions get tangled in with what her brother is doing or how crazy he may be in the head. All I know is that if that were to happen to me and my dad was around.. things would go down.. lol haha including the boy..
But ride it out. If I were your fiance I wouldn't see you any differently. I think you're doing the right thing and being a real man. (This is what every woman wants) I hope everything works out okay. Make sure you take notice to what I said about the courts and your computer. I know that the judge will not be a moron, well hopefully. Good luck sweetie!
