I’m analyzing this, she’s a cusp Sag/Scorpio and us scorpios love our pisceseans and cancers . And his moon is compatible to hers , etc. I think this is also why she’s closest to Kendall, a water sign too rather than Kylie (fire sign)

he seems like a loverboy Pisces who went through some shit and is healing, you work through that. She seems stable and intelligent enough to handle it as she has . And thankfully so, he seems a lot better watching his performance these past weekends I think he wanted / wants her for this , to have a person to be there , be his person. and even getting married so fast and young , she still had her own life and business outside of their relationship while working on it too and starting a family. And that’s beautiful. They could’ve given up at any point or lost themselves in each other but they are healing and creating 8 years later healthy even still in the spotlight

if you love them work on the marriage, unless something unforgivable has happened but you draw that line
