I am only 4 months in, myself, but...
No, you are not being unreasonable about the FB friend. Right now he should be doing ANYTHING you need to establish your feeling of safety. Un friending some random " friend of a friend" on FB should be a no- brainier. Why is it an issue? What does he say? Something isn't right.
What are you doing for yourself, to heal? Are you in IC?
And, gently - if his IC gave him a task to do, why are you reminding him to do it? He needs to be allowed to do it or not under his own merit, to show that he is remorseful and working hard( or not) then you can have a clear picture of his priorities. Give him the chance to show you.
Ask for what you need, then step back and watch what he does. Judge by his actions.
Nailinmyforehead - We are both very outgoing gregarious people, and as long as I know his association with people I'm not bothered, maybe I should be ... I will take into consideration and maybe a fb break is the way to go.
You are not being unreasonable all. I'm so sorry you are going through this right now. (((Hugs)))
I did go buy "Not Just Friends" today and started reading it. I told him I want to read this one concurrently, and he tried to say he wanted to finish the other one first, I was like No .. we can read more than one of these at a time, it's not like they are novels! lol So, he agreed to read it. I told him we could each read a chapter or section, then the other one could read it and discuss. We haven't really had much good discussion yet, still reeling!
