Don't worry. Baby will drink milk when she is hungry. She will cry for a short time and afterwards she will drink again.
I also have the same problem. My baby doesn't drink bottle whenever I'm around. I read the posts in 母乳餵哺. Some mama has the same problem. They will spoon feed or cup feed the baby when she grows bigger. I guess I need to follow their experience as well.
BTW, sometimes I feel very sweet that my baby only likes ME to feed her
my husband and my mother also asked me whether to stop bf when baby is 6 months old.. i'm still thinking... baby is drinking quite ok with full bf. also, bf is more convenient (no need to wash bottles no need to make the milk ). and most importantly, i'm going to miss the feeling with baby...
