I mean he can only do so much. For example his fuckinf parents literally made him stay away from his husband. Had control of him and refused to let him see him only until their health was on the line. That says a lot. They don’t let him grow, or mature, or experience anything as an adult or with the seme. So it’s going to be a harder process for him
Spoiler:
He has had character development he’s such a good parent in the raws and loves his son this is the only time the author draws him as this type of parent for some reason and he gets better immediately after
I don't think the uke is ready for a married life.... He is still childish and immature. Hoping for a character development soon because poor seme doing everything on his own
