Bravery or stupidity??

Whether good or bad I have told Jon exactly what I think of him...along the lines of, "you are a waste of space"(he did tell me once i was a "waste of skin"),and then locked myself in the house! Not brave I know,but I would do anything to avoid conflict for myself but no one hurts my kids without me getting involved! No response so far...strangely enough...I did say some things I do feel we're a bit strong, but no one ever tells him what they really think, there is some sort of unspoken agreement that everyone knows everyone hates him,but when he talks to my kids they are polite back, are they scared, or is it just stupid British politeness...
