The facts are that Britt needs to see that she is a perfectly fine wonderful woman and wife and really has done little wrong for her husband to be acting this way. Once she realizes that and sees that is when she will make her biggest jump forward.
It is her HUSBAND that needs to make some drastic changes here. Since he isn't on here asking for advice, then we need to show Britt what works best to bring him her way.
It is NOT the route she is taking though. She was on the right track, but her mistake was a few days ago when she didn't confront him on his move back in and nip it in the bud from the start. He shouldn't have been allowed back in untiil he showed her why she should allow it. Once she grasps how FREEING to a person's soul that type of attitude is and that the fear she had is only a boogie man, then she may stay stuck in limbo land and waiting on him for who knows how long. Plus he can now leave again because he hasn't had to pay a "price" for his actions. NOT GOOD. (which doesn't work)
