If your husband happens to bump into this lady while out shopping, etc., then it is fine for him to be pleasant and talk to her. If she is always around and he perpetuates the conversation then no, he should not encourage her. Realize your husband loves you and what you are feeling is jealousy and you consider this lady a threat. Trust in your husband and as long as he simply bumps into her and she strikes up a conversation with him he can be pleasant, but make an excuse and keep the conversation light, short and then leave.
