Preflop: raise aces gets reraised, what now?

[KINGOFINLAND]

6handed today. We have 100BB stacks and the opponent just sat down, but I knew he is a good player.

I have AA UTG and raise it to 4BB button reraises to 12BB, others fold it back to me.

I hate pretty much every option here, reraising limits my hand too much and don't like slowplaying here.

Thoughts?
