Do you have a way of verifying if this new knowledge is true or not? Do you think just watching it over time will tell the truth? If so, you are OK to just wait and see. If it affects future actions or your part, you might want to be particularly careful, in case it's not true. Do you remember the saying, "Don't throw the baby out with the bath water?" Meant to not make too much of negative news...leave yourself an option of carrying on with the relationship if it's not true.

You are right, however, to be careful of yourself and your feelings. You are the only one who can really do that. Best wishes to you, dear!
