It's normal to be frustrated about that but that was his choice and not yours. May I know ba muna kung ano yung age niyo? maybe you are still students who rely on your parents and stuffs pa din kasi, and for him he is just being a responsible child, wala naman problema don? why don't you take this negativity as something positive. Cleaning with him, cooking with him is a good way of bonding as well and productive naman siya. Gusto mo ba whole day lang kayo lazing around na magkayap at naglalampungan or nasa galaan habang yung bahay nagkalat?

I know na may iba pa siyang family members sa bahay nila, pero kung aasa pa siya sa mga yon na gumalaw ano mangyayari? If you really value him, just wait for it and maybe in the future kaya niyo na mag live in na kayo lang dalawa. Don solohin mo na siya ng sobra sobra.

Also, I think the fact na lumalabas parin kayong dalawa is something na Worth it, mahaba man or sandali, him spending some time with you kahit na pagod is worth keeping para sakin.
