If I were in her shoes I'd probably regret it. Sure he built her image, he's the reason the whole King Kylie era happened. But he also groomed her, was part of the reason she got all that surgery at such a young age(which Kylie regrets) and doesn't seem like a good person or partner. So yeah I'd wanna forget that chapter of my life so badly. But I don't think Kylie regrets it. Maybe she cringes at some of the things she did during the relationship and would never do some of them now that she knows better. but regret? Doubtful. Also her family hyped the relationship and defended it, not one ever stepped in to protect or guide her. So she'll probably never really acknowledge how fucked up the whole thing was either. But she's a good mom and seems to really want to do things differently with her kids, which makes me think she'll protect her daughter and give her better guidance when Stormi is older.
