Am I a wuss for wanting to just fold here?

It's a marginal situation, I think. You're most likely barely ahead/flipping, or way behind. I don't think it's bad to just let it go.

i would call and not look to fold on blanks

I'm just worried that this is gonna happen a ton. Any 7, 5, 2, diamond (a 6 is a bit iffy too) and I'm gonna have to fold the turn. So around half the deck is bad, I'm not sure my hand is good right now, and there are two streets left for him to either catch or bluff me off.
