The only reason to remove content should be if the content itself is toxic and promoting harm.
What you've posted appears to be, put simply, well executed writing of an emotional topic. You're not even actually showing toxic behavior or relationships in what I looked at- not that people don't have right or reason to have an emotional response. But at the end of the day anything can be a trigger, and emotional and complex relationships are VERY reasonable to expect from stories.
You are also well within your right to explore your own experiences, and feelings! Nobody should be telling you not to just because they don't like it.
(when I say "anything" I don't mean it as dismissive, only that creators cannot be expected psychic levels of forethought. But im otherwise pro-warning, and for airing on the side of caution.)
