Someone who analyzes the details and searches for clues for a living had better have a few reservations about a notorious player who's heading into a third marriage and has only been their significant other for under a year. I like Castle too but he isn't a realist, he's had a posh life and it has left him spoiled and under-prepared in many ways. It isn't as though we haven't seen him be controlling or even taking her for granted once the relationship began. Kate was also the one who said she loved him first (as that bleeding from a bullet wound moment hardly counts) and also gave Castle a drawer at her apartment. She's been hurt before, of course she's being (overly) cautious. She'd be crazy not to be.
"...the only person to blame is A.J. Cook." Yikes! A writer worth their salt, especially a team of professional writers should have no struggle constructing two differing backgrounds for a male and female characters -- especially on a series that's spear-headed by a woman. As for Morgan being a stereotype, he might have been in the first season but he's evolved beyond the "action man" of the team. He's a different type of leader and a fine asset to the team as he's matured.
