This might just be a projection from my very early relationships, but I heavily assume Leanna just wanted to enjoy her young life without being bothered by responsibilities, because she still had a childish mind as a young adult, means easy to influence and to make her laugh. Immature stupid "jokes" from a famous guy (power positions are sexy), who constantly pretends to be the Know-It-All without really knowing him? Perfect manipulation.I've encountered my fair share of women who thought certain men were funny when I very much did not find them to be, but in Leanna's case, I think it went from finding him funny because she didn't really know him to finding it funny to laugh at him because she realized what he is.
Has she just adopted his opinions and toxicity? Who knows! But she used it to turn against Phil at a certain point, which was glorious.
So, now imagine yourself in her early shoes. She looks at a mature adult who should know how the world works, is an okay-ish looking guy, behaves quite differently from the rest of males, has many opinions, is in a power position, has his own condo and seems to make good money with videogames, has maybe a Papa Bear feeling, quite energetic and constantly moving, makes jokes all the time.
To quote Phil, they had way too different interests. She wanted to travel and such, and he wanted to play videogames. While Leanna developed maturity, Phil decomposed to an old lazy bum who's good for nothing of interest.
There had to be a time when she thought to herself: "Hahaha, oh Phil you're so funny. But now seriously, I need an adult partner. So please stop sitting on your ass all day and get a job." and realized "being funny" in her own opinion is the only positive trait he has and this is not enough in a long-term relationship.
She came home, Phil yelled at games. She started a soap business, Phil yelled at games. She made friends (I assume), Phil yelled at games all alone.
This would maybe be okay if she hadn't figured out his self-centered assholish behavior is not an act and made no stop in their relationship. "I still wait for my apology!" "Uuuuh, NO! ACK ACK ACK".
There had to be a limit to the toxicity she could tolerate in her private life, especially when it comes from an insecure manbaby with the tiniest balls and can't catch a teaspoon of responsibility.
Leanna has a personality and a certain strength, I'm sincerely happy she moved on, I wish her the best. Phil Burnell is not fit for a relationship with any sane strong waifu.
Then we got Khet with the Asperger.
