Right from the start, Kyle Richards was suspicious of her sister Kim ‘s boyfriend, Ken Blumenfeld. In Real Housewives of Beverly Hills Season 2, Episode 19, Kyle listens to Kim’s reasons for wanting to move out of Ken’s house, but she seems skeptical that the problem is all one-sided. “You’re also difficult,” Kyle tells her sister and wonders why Kim stays with Ken if he puts her down.

Regardless, somewhere between the launch party for SUR Lounge and Kim’s stay in rehab in December 2011, the reality star moved out of her ex-boyfriend’s house. The couple had many problems, from the fact that Ken retained a Match.com profile while dating Kim to his DUI arrest in 2009 — which he also kept from Kim.

According to what a source told People, Kim was moving from one friend’s house to another, “basically homeless” before she checked into rehab.  On January 10, Kyle told Ryan Seacrest that Kim was out of rehab and doing well and that she had definitely dumped Ken.
