Rule out set over set. It does happen, but never for one second allow it to enter your mind. It doesnt happen often enough to be worth your consideration.
Then, when you're given the chance to see the turn cheaply, do so. If you are really sure you are facing the straight, then you have an immediate cheap chance to draw out, because your opponent stupidly raised a small amount instead of forcing you to accept a fundamental theorum mistake to keep playing. She isnt going to fold that straight because the board pairs up, so your implied odds pay for the call and then some.
Repeat on turn: if she goes allin, dump the hand. Check/call a small bet. IF you are sure she is stronger. If you aren't sure, then simply call her allin and gather some data, albeit at a price.
My guiding principle in these situations is, if I think I am beat but have a strong hand that can improve to a sure winner, I keep the pot small and see what happens, or I let it go and live to fight another day.
