Kim is a dumb groupie who lucked up and married her target. She would leave her sons at home to chase Randy around the country to make sure he wasn't fukking anyone else, turned a lot of his fans off with her antics against them, probably doesn't care much for his first kid, takes over his social media accounts to post half naked pictures with long pontifications about how great she is to him and thinks the sun shines out of Randy's ass.
On the other hand, Randy is calmer now, so you gotta take the good with the bad.
