But between the "quit your job" - "what do you mean, go live with you in Georgia" - "I'm avoiding your calls" - "blah blah ultimatum" I just couldn't handle her anymore and I was glad when she became less of a presence.

It was definitely a relief when she's off the screen. It's poor characterization, imo. They didn't want Raylan having a functioning relationship because that's not who he is right now, but it meant she and him had to clash. they just didn't do it in any interesting way. but at least they didn't kill her, which is what so many other shows do.
