The first couple of seaons the wives seemed happy and to all get along really well. Now they all seem unhappy, and it came out that Meri and Janelle have never liked each other and still don't get along. Have things changed that much, or have they always been unhappy and just edited it to look like they liked each other in the past? According to their book, Meri only likes Robin, and barely tolerates the others. I just wonder what the truth really is.
