Your fiance, in my opinion, has two options. If a man (you) is making her choose between him and "the dog" as you refer to it, she can either:
A: dump the man and keep the precious pup who will love her unconditionally
B: dump the dog and keep the man and be sorry later in life
If this were me, YOU would not be thinking of YOUR options....YOU would not have any. I wonder if she has consulted with HER family....maybe she does not have any? Please have her contact me, I will be happy to help her out with some friendly advice.
Your post disgusted me. I barely read through it all.
This poor little pup ... you hit it??? Look at the size of you..and look at the size of it. Of COURSE it bit you...what ELSE does it have besides teeth to defend itself?
You want children, you say? I think I best keep my trap shut about what I think of that plan. Just use your imagination.
Shame on you.
