I generally like the show Married at First Sight but honestly what questions are asked before 2 people are thrown together? I think you need someone who can see these people for who they are. I don't know what the heck you re doing mixing up such unlikely couples.
2 have never been in love, 2 are having serious trust issues, one couple is a firefighter regular normal guy fixed up with a Kim Kardashian wanna be spendthrift. Who did that?
Mryla should be alone for the rest of her life. Anyone who doesn't like dogs is not to be trusted. PERIOD.
There may be only 1 or 2 compatible people but hard to tell. Myrla has got to go.
