Well, if it ends breaking up and you still have strong feelings for eachother she'll see that eventually and fall in love with you all over again. Basically, all I can say is, Give it Time. It worked for me and a bunch of other friends.

Well if her dad or brother picked up and said never to call again, I'd just tell her to call me or I'll ask her when it would be OK to call.

As for catching her in bed, I'd just tell her we're over. It's better than resorting to violence with any of them.
