'How did that ever happen', lol. If you keep asking the guy smokescreening and trying to prop up this narrative where he was just a decent, regular guy that found himself sandwiched on all sides by crazy women, it's never going to make sense.
This is because the narrative of a pathological liar will never make sense.
If you look at the sequence of events, it's evident enough. A prescription-and-alcohol mixing flunkie wanted to rob a new cradle, as his current almost-child-bride was just getting too old and conscious of his spiraling behavior. Enablers only, please!
Who better to enable that, then a fresh 20something pair of pert tits with severe sadbrains! Owetax figured he could probably keep that situation under control, and as usual put zero consideration into potential long-term consequences.
When Ashli ran for it, Owetax was prepared, and power-moved to establish that Ashli was out of her mind, and leaned hard into character assassination. She wasn't the upset wife who bailed on a toxic relationship after three contiguous weeks (which included one of the U.S.' most family-centered holidays, Thanksgiving) of him being in Utah to fuck some new cooze under the pretense of 'researching business opportunity.' No, she was a kidnapper and a loony bitch.
Owetax raced to legitimize everything by passing the keys to the castle progressively over to Logan. In his poisoned logical process, how could he have POSSIBLY been fucking Logan in November if he's totally legitimizing her as a business partner amirite?
That, Belinda, is what makes sense in 'how did that even happen'.
