Russell,
No reason to explain your why's or anything else to anyone else. This is a personal matter between the two of you which never should have been made public fodder to begin with.
If some expect reasons, explanations, etc. then that is their issue alone. We are each free to think and judge as we see fit and no matter what is said or done none of us were there (except the 2 of you) and so additional input from others isn't only not needed it is unnecessary, imho.
Personally for me... my feelings on trust are based not only on what is said but also how one acts. And I agree with Oz, trust is given until a reason is given not to trust. It may be initial and hesitant trust but until proven as a mistake in judgment (my judgment) it is given. Over time that trust will either be confirmed and deepened or it will be disproven. But, once again that will be based on my experience with the person and not on some others thoughts, etc.
So... agreeing with Oz I guess makes me "odd subbie out" but what else is new... *laughs*
