This reminds me of that particular manhua where the Seme is a literal psychopath, and genuinely aware of what he is and his nature that he cannot change.
This type of heavy content is not for everyone.
Caesar is a mf psycho that literally cannot grasp the concept of "gentle love", his fucked up upbringing amplified it as years went on and you can say he's literally insane with how he thinks of things. What's normal for the Uke doesn't add up to his formula that all he knows is how to inflict dominance by rape and torture, should we be glad he didnt cut off his limbs this time at this rate, death might be the option for a happy ending lmao.

i feel like if his upbringin was normal hed just be a wee bit crazy. like possessive n shit n needin to know that his love is in fact reciprocated. as you said with his upbringin it fucked him up immensely and he doesnt really know how to regulate his emotions and feelings aside from inflictin violence and bein domineerin towards people. its really sad tbh
I see the points of other people basically being mad about how Ash literally FORCED Lyle to admitting about the proposal.
But I can also see the reason why he would do it, they both experienced the bad ordeals that happened because Lyle, as sweet as he is, is bad at communicating when something is wrong. He keeps it in, piles those emotions inside, until he explodes from overthinking and do the unthinkable. As an individual who is very bad at opening up, IT'S NOT EASY, even of people say tell me when something's wrong and such— it is easier said than done. Ash is very vocal but Lyle is still learning and as obvious as it is he is still bad at it despite promising he would say tell Ash if something is wrong. It's not that easy to break out from the loop you conditioned yourself to and due to his upbringing this is proven as a difficult challenge for him.
Now looking at Ash's perspective, he very much so wanted to wait for Lyle to tell him what's wrong, but as his significant other and knowing his issues with communicating how he feels, I can understand why he had to 'force' him to say what is wrong. Now, I wouldn't justify that f*cking the truth out of him is right but if he knew that Lyle was planning to propose he wouldn't have done it either— as we all know guys LYLE IS BAD AT KEEPING SECRETS, he wears his heart on his sleeves in front of Ash.
For both of them, one that has no troubles communicating with what he feels and the other being an overthinker that has issues communicating when things are rough— you will see frustrations on both sides no matter what. As we have witnessed on Ash's ex, their relationship almost had another tension if Ash didn't become forward with Lyle running away.
