Min,
wow, thanks for sharing. I'm glad you had your bf/hb for support during that time. I guess it's a side to think about, "what if" we (parents) aren't around anymore. My mom did ask my bro, when we were younger, what if they were both gone and I was still in school...he said, "just use your cpf to pay for her education lor, she can take care of herself". So...haiz...some siblings have also like dun have.
BUT, I must say that since he started having his own children, he's been "nicer" or caring. And we have had good conversations when he visited us in US. He's generally a nice guy. Now back in SG, we see each other like 4 - 5 times a year...maybe.
