One new thing that strikes me about the first article here, is that Molly did get pregnant when she was with McGinn. She ultimately had a miscarriage which could have been caused by all the medication she was taking. One miscarriage at a young age during a precarious health situation did not mean she could never have her own children. Yet she uprooted her life in order to snare the perfect ready-made family.
There are so many ways this story is a Greek tragedy and this is just one more element of it - she could have had her own baby; she could have found a way to live a normal well-adjusted life with the right emotional and medical support. Instead, she pursued her dream in the wrong way and sabotaged what she had when she achieved it. Her parents were complicit in this - they could have supported her by telling her to wait, look after her health and build up her self esteem, and then pursue her dream of having a family. But instead, they let her fly off to Ireland, lie her way into a responsible job and a secure life, just so they could put the label of "good mother" on her. Purely destructive and self-sabotaging every step of the way.
