Saping, I could feel that you are very frustrated now..
But one thing i admire you is that you are quite 'honest' and 'responsible', otherwise, you wouldn't have been so '煩' la.
Saping, one kid jei. Don't label ('認定') the baby is a burden to you, he can also bring you lots of joy beyond everything. Accept him now and wait for his arrival. If you keep thinking that's a burden (沈重的責任), then you will drive yourself and your gf crazy, too.
Ur attitude needs to chang a little bit tho, if you want to talk in BK... you seems a bit too straight forward, even this is a virtual world (虛擬世界).
