The story between Marshall Mathers' and his on-again/off-again Wife Kim Mathers has been an ongoing saga for almost 20 years now, all the songs that mention Kim by name, or by reference, are purely Marshall venting... and getting paid for it.
Basically it's just another person's private life being publicly aired, you'd be hard pressed to find a Celeb that doesn't utilise their private lives to benefit their careers or conversely to have it happen to them without their consent.
Personally, I love the track 'Kim' from the Marshall Mathers 'LP'

, but I've basically stopped listening to anything else he's produced since D-12 World as that was a horrible album and his work has been in a steep decline since, or maybe I'm just too old now and the rap that I listened to no longer exists

because Pop music for this soon to be passed decade has been the most manufactured crap I've ever seen

and it looks like it has certainly influenced Eminem's material - that's for sure.
Albums I own:
1. The Slim Shady 'LP'
2. The Marshall Mathers 'LP'
3. D-12 - Devil's Night
4. The Eminem Show
5. A multitude of unreleased downloaded tracks, Demos and Acapellas.
The only other album I'd consider getting is the 8 Mile Soundtrack.
