Good morning, question

So my husband has been getting harassed by a female, they have been friends for a while n she has a boyfriend n a baby n she n my husband used to talk to eachother about life n relationship problems so I noticed that she had sent my husband a text the other night saying that she misses talking to him (because he hasn't Ben speaking to her the way he used to because him n I are way better now than we ever were n we promised eachother that we would speak to eachother only about everything concerning our relationship n not confined in someone else from the opposite gender, so when I saw the text I immediately got on detective mode to see what this girls deal was because I didn't like her text n I text her as if I were my husband n acted like if he didn't want to be with me anymore n she jumped right on that "oppening" n it tirns out that she caught feelings for my husband n text him (me) that she wanted him, I showed him the text n he said wtf she's crazy then he said he never gave her any indication that he had any feelings for her or that there was a chance for her there, he said that their text were just on a friendship level n they just shared their drama issues n gave eachother advice than he blocked her from everything n erased her number but before that I text her back as my husband again telling her that I (my husband) didn't ever view her as anything but a friend n that I'm happily married n have eyes for no one other than my wife(me) n that I was sorry if my friendship with her gave her the impression that I had feelings for her or liked her in that because I didn't n that I will not be in contact with anyone who has feelings for me so she needed to not text, call, FaceTime, Skype, email etc. n she's then she text him from a different fake number saying that she doesn't understand y he blocked her n that she's saddened by it then she kept texting him from different numbers after she saw that he wasn't responding to her n she was still blocked 
So here's my question how would u handle a clingy obsessed person trying to be in contact with ur husband even after she's told that nothing will ever happen n that he doesn't want communication with her, he's been ignoring her ever since I found out her end game but she's still texting, it's now been from 3 different numbers that she has text from n everytime she realized that her number is blocked she goes n makes another fake number to text him from to see if he would respond to her. 
It's getting super annoying to me right about now n I feel like texting her n telling her to back the fuck off but I'm not the type of person to go all ghetto on someone but I would tell a chick off n stand my ground if I had to
