I’d fold, but I think there’s a lot of room to improve your thought process on earlier streets. For instance:

“im on the button with a decent hand so i raise… im expecting 3 bet or fold”

If you actually expect a 3-bet or fold response, and you are going to fold to a 3-bet, then having a “decent hand” isn’t relevant, as you’ll never see the flop. The decision to raise should be based only on how often you expect folds and whether you have a significant blocker to 3-betting ranges.

That said, I don’t see why you should expect a 3-bet or fold response. It’s not like the blinds are especially short-stacked. Why wouldn’t the big blind call with plenty of hands getting 4:1 or whatever?

More importantly,

“flop is pretty decent for me and i c-bet”

Just because it’s a good flop for you doesn’t mean you should bet. What does betting accomplish? Will better hands, or hands with significant equity, fold? Will you be ahead of Villain’s calling range? Do you have a plan if you’re check-raised? I’d pretty seriously consider checking back the flop.
