Agree. Also think the spying that LE says began in 2014 was probably Jake W hacking her computer/cell phone and social media accounts. He probably became very possessive and controlling over Hanna. If he was out on the road driving his truck, as he claims, he may have been paranoid about her activities while he was gone, thus the hacking and spying. JMO, Jake often speaks half-truths. His claims that he quit his job because HMR was upset that he was gone on the road all the time are probably the opposite. He was the one obsessing, becoming jealous.
Something happened around that time that made her end the relationship and move back home. She was maturing, craving independence and probably felt confident enough break up. Just speculation on my part, but the spying/hacking might have come to the attention of her mom Dana, who demanded she leave the Wagners and come home. It could have also been some escalating harassment and emotional or physical abuse from Jake, too. Dana probably wouldn't have tolerated that, JMO. She wanted her back home, finishing school, getting on with a more normal life.
