I'm thinking that Emily's emotions really got the best of her while the show was airing.
I believe she LOVES Brad. Trust takes time...I think once she "feels" and experiences Brad's love in the real world....she'll be fine with making the move to Austin.
I also think Brad loves her. I believe he has "what it takes" to be a great husband to Emily and a father figure to her little girl.
Who knows...all I can do is hope and pray for the best for Emily and Brad (and for others as well).
