is this normal?

i find myself being semi-secretive about the details of wedding planning.

maybe it's because i'm afraid people aren't interested in hearing me blab about my wedding. or maybe it's because i'm afraid they won't like my ideas. or maybe it's because i'm so dang independent. or maybe it's because i'm afraid it's not really real. [am i really allowed to spend my life with someone so great? do i really get to spend a whole day with my loved ones celebrating this incredibly special love?]

my future mother-in-law keeps trying to excitedly ask me about things like flowers, ceremony decor, dresses, etc. etc. & i keep giving vague answers. and whenever someone else asks me "how are wedding plans coming along?," i say a couple words and then ask a question about them to change the subject. a person has to work really hard to get a real answer out of me. i basically want them to prove they are genuinely interested and will genuinely like my ideas. otherwise, my lips are sealed.

so now i'm just wondering if this is normal.
