Personally, I think PF may have been becoming more and more abusive toward her. It most likely started out as emotional abuse, but kept getting worse over time. Eventually, he may have pushed her or left bruises from squeezing her arm too hard. She was a strong, intelligent, successful woman, and often control freak men will get involved with a woman with those types of characteristics and then start, very gradually, but very systematically, tearing her down, trying to destroy her self-confidence and isolate her from the people who love her. I think he wanted to keep KB, even though he was never faithful to her, as someone he could see when he wanted to be with someone, and someone he could beaway from when he wanted to be alone or at the farm. He wanted it both ways. Maybe KB got a clue he was cheating, but it is not always as obvious with men who randomly cheat. KK was far away, so that relationship was basically a virtual relationship with some hook-ups. I think Kelsy was strong enough emotionally to decide to start separating herself for him such as buying her own home. I think he could not stand her rejecting him (even though he didn't love her), and starting coming up with a scheme. He tore her down to others and discredited her as a mother. Tried to make others think he was the primary caregiver. Most likely he resented her job because it still gave her independence and the ability to escape from him. Often women who realize that they are in a dangerous relationship will photograph injuries or destruction. Often the abuser will tell the person that they are crazy and will try to make them look crazy to others. This evidence will prove to others what they have gone through. I think possibly KB's family has some evidence of his emotional and physical abuse and that is partly what the wrongful death lawsuit is about. I don't think it was about the child other than she was a weapon the PF could threaten KB with...her won't let her take her out of state, he will try to prove her unfit and so on. I think this was about PF as seeing KB as his possession and he was not letting her escape. Not because he loved her, but because he would not be rejected by her. Poor KB made the mistake of underestimating just how dangerous he really was, and perhaps she felt trapped into staying there because of the baby.
