I have to disagree with how you're framing this. Although the bottom does have abandonment issues you're making it out to seem like he's some manipulative asshole when that is not the case at all.
He genuinely started to consider dating Yunho. And if anything, unintentional or not, the TOP has been the most manipulative one here. Throwing tantrums and saying the most hurtful shit to force the bottom to change their ways is basically abusive. He's been actively pushing on a sore spot (the bottoms fear of abandonment) to get his way but when he does get his way he realizes it's not how he actually wants it and distances himself even further. THAT is the most selfish, immature and miserable thing I've ever seen.
And this isn't for a lack of communication on the bottoms end. Because he actively listens and he ALWAYS asks questions and wants to talk it out.
Yunho has been unconsciously emotionally abusive for these last few chapters but he's so immature and in his head that he thinks he's the only person hurting here. Or worse, he thinks HIS feelings are the only important one of the two.

I’m really behind on the emotions here .. like the top is insecure correct? But the bottom is also trying isn’t he to fix things ???Miscommunications? I don’t understand what kind of emotion I should put in this ??
