First let me say that I've filed divorce papers and plan to serve them when they've made their way through the courts--about 3-4 weeks. I'm putting this question here because of H's past EA and this forum gets more traffic than the D/D.
The reason I am filing is that the marriage has broken down and it is beyond just my control to fix it. I've repeatedly asked him to give me a sign he is willing to work on this relationship and he has repeatedly either not answered or said "no". I guess I can take a hint? The final straw was my second call with Steve H., where Steve suggested trying to get H on the phone with him. We rollplayed ways to present that. :

: No response, no action.
Ok, so on to my question.
(Background: During a particularly low point in our relationship in 2005, H went back to Oregon to attend his HS reunion and started an EA with an old girlfriend--someone he never told me actually WAS a girlfriend--he'd always passed her off as just a friend. This went on for about 18months when I finally hacked into his chat/email and busted him. I'm fairly sure there has been NC since then.)
So last March, H goes back to Oregon for a few weeks. He had some family obligations and he was looking for a job since he so desperately wants to go "home". (Old girlfriend does not live in Oregon anymore BTW....).
Shortly after he returned, a bunch of emails and phone calls from a childhood/neighborhood friend started showing up. Wow, I felt like it was deja vu all over again! I asked H about them and he said that this woman was just a friend (where have we heard THAT before), she had become friendly with his mother (this much is true...) and that she was 'ugly and not his type'. Hmmmm...
I repeatedly stated my discomfort with this and he repeatedly sort of poo-poohed me by saying I was making a big deal out of nothing. However, I do still monitor the phone logs and emails and for the most part, communication was one-sided. Mostly her trying to reach him. His communications to her, as far as I can see consist of asking for further advice and help about getting his Mom into assisted living, and when this woman's father died recently, he sent a short sympathy note. It was very impersonal and focused on her father who he of course knew while he was growing up since they were neighbors.
I've erased about 7 messages on our home voice mail--from her to him. "Call me!" I've seen several emails from her to him "what's a good address for you? I sent something but it got returned (we moved about 2 years ago). He never checks home VM--only I do, hence it was easy to just erase them.

So the most recent email (the address one) and then today, a VM message on his cell phone. "Mr. OH, finally, YOUR voice and not OH's. Call meeeee".
Divorce papers or not, I'm BEYOND annoyed. Not only has H demonstrated his boundaries SUCK but this is getting ridiculous!
What I want to do is send this woman an email..."please stop emailing and calling my husband". Short and sweet. It might not do anything but he's discounting my discomfort and she's like a pit bull who won't let go about getting in touch with him!
Should I do it?
