Meri and the catfisher
One thing I find interesting is that neither Meri or Cody is willing to own that Meri cheated, at least emotionally. Since they never met, and it was not actually a man, that means she didn't actually cheat. The thing is, she did cheat. She thought she was talking to a man, was in love with "him" and made plans to meet him. Purely accidental that the meeting never happened. Until they are both willing to deal with this they will never be able to resolve their issues.
I am not even criticizing Meri. I think she is in a very bad place, feels very isolated and unsupported and resorted to getting the validation she needed from strangers online. Very sad.
