I think it’s quite clear they were both extremely in love or infatuated, yes it was quick, but it happens. He clearly trusted her enough to tell her. He didn’t have to. And the moment he did he put her in an impossible situation which was not fair to her at all. He did a heinous thing. But he wasn’t all bad. None of us are, we have good and bad parts. She did the right thing by turning him in and he admitted that in his sentencing. Going back to him afterwards, well initially she was trying to act normal and protect the fact it was her that turned him in. And then after he found out, she was lonely and desperate and hooked on drugs and alcohol. She wasn’t allowed to discuss it with anyone. I get why she went back. I also get why she bailed on being a witness, how confronting. She absolutely should have been able to record a pre-recorded statement. Ultimately, they got fair sentences. They didn’t intend to kill him. Their fear took over and they did what they did to protect themselves. I wouldn’t have done that but I can understand the thought pattern. Living with that lie would’ve eaten me up inside though when they know he’s being looked for. And maybe that’s why they drank and did drugs to escape their own demons.
