Re: forgiveness. If you think she is pushing ahead because her affair is unforgivable, it will be far more useful to demonstrate forgiveness, rather than show her an article. And I think you are already doing that. The article would be "crowding her" as you put it.
This fits with why she resists the offer of help at first--she may feel she doesn't deserve it. I think it is a big positive sign that she accepts the help at all. As for the hugs, she may again feel like she doesn't deserve one, so she resists even if she enjoys it. For now, just be glad she doesn't recoil at your touch, as my X did.
Your 180s are working--you will see it in small improvements in your interactions with her. Accepting a hug, accepting help. Just keep doing it.
