Even though I don’t have the full story, o can take a guess based off of the bipolar diagnosis. He was probably having a mixed episode (so that’s and up and down at the same time aka Hell) and that proposal was an attempt to anchor himself to something real. Except since bipolar episodes can happen at any moment some people might not be awake when their partner has one.So he asked her to marry him then killed himself?
Did she turn him down? Or did people troll in response? The later tweets call her his ex-girlfriend, is that references to his death, or had they broken up already?
Did he just realize how cringe his asking her to marry him over twitter was and that pushed him over the edge? Is this the first confirmed instance of terminal cringe?
Unfortunately, even if she were awake and said yes, that probably wouldn’t have stopped him from killing himself. Some bipolars are on a death spiral and it sucks to think about, but bipolar is a purgatory of its own.
