Sorry for the double post, actually a big portion of DB is rooted in making the walk away spouse face their choices.
Going dark is just another way of saying:
"fine run away, see how you like it"
LRT is well, LRT enough said
Even simple things like stopping R talk tell the WAS: "ok this is what you want, go ahead"
Here's the thing, Jake doesn't have to be a jerk.
Instead of saying:
"I checked up on you! You have been lying, it's him or me!"
He could say:
"I noticed on the bill you are still in contact, I guess he means more, and I can't compete with that. I don't want you to leave, but I think you should take some time to consider who means more to you."
