I agree with some of your points, that he should’ve worked through himself more before having a baby. But also consider, sometimes our traumas come out and manifest in certain conditions that we may or may not be aware of or expect. There is no right way or timeline when it comes to dealing with trauma. At the end of the day, he and his partner worked damn hard to get through it and become better people and parents. :) (also this is lowk not a psychological manhwa so)

The alpha is not ready to have kids. I’ll start right there, He’s too young and too early to have kids, he could have at least focus first to overcome his trauma if he really want to start a family but no, he rushed it, things got out of hand. Okay I’m not invalidating his trauma from the past okay? I’m just saying, his omega is pregnant but instead of helping him through out this pregnancy, he’s the one being taken care of.
Fist he woke up his pregnant omega in the middle of the night instead of waiting till morning and the worst part is, he didn’t even explained properly what the dream or worry is about, he could have just waited in the morning to talk to his omega like bro your the man of the house, you gotta learn how to man up especially now that a kid is otw
Then this childish tantrum started, so childish he started to become controlling, anxious, and stressed… this mother fucker, did he even think or worry that he might be stressing the pregnant person also? This is exactly what I meant when I said he’s not ready to have kids yet, he’s a kid himself, how can a kid have a kid? Its weird lmao
