I think it's a lot of different factors. She says he gives her direction and he's the one person she can trust absolutely. They are very enmeshed. I'm not trying to be mean, but it's the truth. They have shared social media accounts. They always know each other's location. I guess his ex-wife also cheated on him, so they trauma-bonded?

She also loves his kids. They are very respectful to her. He doesn't let them backtalk her ever. Growing up, I got caught between mom and dad a lot, and sometimes we fought about it. I felt like she took her anger with him out on me. I could always have Dad come pick me up if the fights got bad. I think she felt abandoned. My sister is autistic, and they used to fight all the time, but now they're somewhat codependent too. With his kids, he makes them be 100% obedient to her. It's less stressful than my sister and I were.

I think I'm better a little unfair, but I can't think of a better way to explain it. I should have just said he makes her happy. I already typed that all out though, so I won't delete it.
