He is clearly extremely high maintenance and seems to act ****** then try to make up for it with something extravagant and that cycle gets old. On KUWTK she seems extremely nervous of making him mad at times too.
She's got 2 kids, she doesn't need a husband throwing toddler tantrums.
If he acts this way in public, can you imagine what he's like behind closed doors? She'll file for divorce and claim that he was controlling and abusive... I can promise you.
