If you feel that suffocated with him when you only date for a few months then I could say, you're not really into him.. You just afraid of changes no? So you just suck it up with dating Yishin. This is not a healthy relationship when Yishin head over heels almost obsessed with him..
He totally forgot the main message his mother to say is that "be happy". Which part of your life now that have happiness while you follow your father footsteps? Are you happy? You will realize it just after you lose Namin, Typical.
