"She" will find a way and/or excuse to contact my husband . . . bit of a long story, brief interlude with her while husband and I were living apart for a month and unsure of our future . . . they had been conversing via text mainly for months prior to this actual physical interlude. She is and has been involved with a married man before, during, and after my husband, and is so currently . . . yet she will find an excuse to contact my husband . . . she assured my before nothing was going on between her and my husband, obviously a lie, and she is aware that we are together . . . we never officially separated and did not divorce, we are still married and we are together. I have blocked her from his Facebook account, I am tempted to block her number via our cell phone carrier . . . I don't want to anger my husband, as if I am keeping tabs on him or keeping my thumb on him . . . . he only wants to be cordial to her as she works with some of his acquaintances . . . but I do not want contact between the at all. What can I do to legally stop her?? Anything?? A cease and desist all communications letter?? I'm at my wits end!!!
