function of に after 私


sentence : あなただけの私には...今の私はなりたくない

I think it's something like "I don't want to be... only yours now", but the に
there, would mean something like "for me" , "in" , "to me", etc but I can't
see any possible translation where the particle fits. could you please tell
what it is its function here?




> 「あなただけの私 **には**...今の私はなりたくない。」

means the same thing as:

> 「今の私は、あなただけの私 **には** なりたくない。」

「X **に** なりたい」 ("to want to become X") and 「X **には** なりたくない」 ("to **not** want
to become X") are both very simple constructs and the 「に」 and 「には」 **MUST** be
used respectively for the phrases to make sense. Since 「なる」 is an intransitive
verb, you need to use a particle in introducing the indirect object "X".

Let us now replace the X by the actual words 「あなただけの私」("I that exists only for
you" or "only yours" to borrow your TL).

The speaker is saying that, currently, she does **not** want to become the
person described immediately above.
