There's too plenty of past messages I could share but I would share this one as an example. This was from a fight that stemmed from his ignorance towards the plight of women over the course of history. A heated fight and I went to H as a 3rd person to ask him H's views. H is a sensible person, he also said he just discussed the same issue with his roommate. He said he thinks about it nearly everyday. I could make a 1000 miles progress when discussing with H, but no progress except arguments with M. So when I sent M all the screenshots of H's answers so he can compare to his (and because I knew my words hurt others easily when I am angry) I told him to go speak to H and learn. This was his reply:

Dila
H is your friend
not mine
he's a good guy but I don't know him
not like i know you
and based on what you said and how much you've shared with him
he doesn't know you like I do
and you don't know him as well as you know me
I am awed at how explicitly calm he sounds every time he speaks though
judging from your screenshots i mean
... cmon dilu
we were doing so well
DIRUUUUUUU
okay tell me how is Max
yknow how much I like a DIRU right?
my good side can trump my bad side
I'm sure of it
anyways
it's late for you
goodnight

Dila is what he and H calls me. Diru is what he uses when he is being clingy. Max is my cat. Which he loved, and self-proclaimed himself as the godfather of. He wouldn't have left without asking a final picture of Max. I know in his mind he is calculating it. He wants to fix himself and come back, whenever that may be. It's his 'ocd' (I know, I am not misusing it, he is not clinically diagnosed, but it helps to explain). he wants to clear out the mess in his life as he starts his 'improving myself' plan, which he always fails at so far. I call it 'energy sparks'. Feels like he can take on the world at one moment, then feeling down the next. I have a bipolar mother, and I always assumed he is bipolar. or maybe multipolar since he wears so many masks depending on his mood. But deep inside, he is a person really special to me and I can see through him easily. Hence why when we get into arguments and I know his opinions are flawed, I block him. He would come to his senses after a while and see the problem that caused us to fight. And we would reconcile. I call it his 'different suits'. There's the sensible suits, messy suits, angry baseless opinions suits etc.

But still even if I can expect M to do stupid and selfish things like this only to regret it later, H on the other hand, would never have blocked me so the puzzle is still not solved.
