@BL is addictive confessing his feelings to JH at this moment will do nothing but perpetuate his already unhealthy attachment, he has no insight, doesn't understand why he feels the way he does. This separation is exactly what he needs to figure out his emotions, since he didn't need to do that before. MC is actually fantastic in his insistence of JH getting a therapist. Figure s*t out, decide who you want to be in this relationship and have BOUNDARIES based on that, cause friends and lovers have diff set of boundaries and access
If he confesses now, JH still might not realise what he truly feels, but he will go along with romance just to have MC stay with him -hard not to see how fucked up that scenario is
Rn MC can't be actually sure, that JH likes him in a romantic sense, cause you could view that attachment as that of a child to their caretaker (let's be real here) and that is what worries him. "I can't be your only one" - as in mc can't be JH's only pillar of support
