When they first hooked up (via twitter of all places...) the plan was for Evelyn to get pregnant with twins. Even filmed an episode at the fertility clinic for Not Really Basketball Wives. Then Evelyn's celebrity career seemed to take off, and the plan for kids changed. They seemed to really enjoy each other's company, but recently she's been on the road promoting her own career and I think there were some cheating rumors just prior to the wedding. Frankly, Chad's all about me act while cute probably grows old in a hurry. And she may be approaching greater net worth status between book sales and makeup lines and reality shows... Not to mention Eve has a temper of her own (although other bishes are usually the target) and a mouth that makes Chad's F bomage seem tame by comparison.
Putting himself out there and piling on the pressure may have finally caught up with Chad too causing him to do something really out of character.
