Then maybe talk it out. Not leaving indefinitely. Take a step backward and put your shoes on the seme. He does everything for the uke but the uke has never reciprocated anything back. He even blew up on his own birthday not appreciating the effort the guy had to go through to prepare everything last minute.
Had the uke was willing to work things out, the seme would eventually sort his drastic actions because he would feel the uke is properly participating in the relationship.

Reading this comment section and a lot of you are siding with the seme? Like the seme cutting off with his fam? Quitting a job for him? That shit aint healthy in the long run dude. Trust seme will blame the uke if that sht continue. And seme keeping secrets bout the house, the job etc. IS NOT the same as keeping a secret bout uke's birthday.
ANDD ANOTHER THING... GARAM DOES NOT WANT TO COME OUT. he experienced lots of homophobic sht growing up AND YOU WERE PART of those homophobic sht. And you question why he wants to keep the relationship a secret?? Man grow up.
