Anyway she dropped another bomb on me saying she wanted to be “honest” and not sneak around. She’s planning on flying up to see the OM in a couple of weeks. Being an emotional wreck, I am terrified that the EA will turn into a PA. Doesn’t a long distance PA constitute an open marriage?
Newsflash, you are in an open marriage.
You are tolerating her communications and now her trip to visit this OM which will only culminate in them having some sort of physical relations.
What has your DB coach told you to do so far? I'm very interested to hear what the advice is considering you've caught this at a relatively early stage (ie. no physical contact yet)
