Three weeks of misery and three weeks of gain, an engagement ended, and a whole post about what happened in between. That is the opening piece, and the writer does not tidy it into a lesson before the end arrives.
She writes as well about having been the person who did whatever everybody wanted so that nobody would be annoyed with her, and about the partner who told her that people are going to be unhappy sometimes and that this is not always anybody's to fix. It is a small realisation and clearly a very large one for her.
The practical post covers writing advertisements that get read, and its list of what people pay attention to is short and correct: simple, personal, interesting rather than exhaustive, and pointed at a problem.
There is a genuinely irritated piece about classified ads that appear to post and then quietly do not.
Read the one about being a people pleaser if that description lands anywhere near you.
