I think she bought the Townhouse for security and to have a stable environment for her child close to her father. She was trying to make it work for both of them. ImoI don’t know about you, but to me, it is a chore to change an address. Too much busy work and hoping all the changes go through correctly.
As a new mother, driving four hours round trip to work daily, juggling daycare for baby K, she or PF passing the post office in the exchange of baby, changing her PO box was probably the least of her worries, IMO.
In Kelsey’s mind there was something still workable in the relationship or she would not have bought the townhouse in May. JMO.
