Why did bob bryar leave MCR?

Bob left so he could spend time with his new wife. Keep in mind that Matt was the original drummer and intially left right before the video for " I'm Not Okay (I Promise) " was filmed. Bob at first was meant to be a temporary replacement but the guys loved his playing so he quickly became a memeber of MCR. bob has been with the band for about 4 years now, and as being that he is now married and starting a new life with his wife, he decided to take a break from playing music, and enjoy his new life while he can.
