can't help

Unable to resist

Can't help means to be unable to prevent or resist something, often despite one's intentions: I can't help laughing when he does that, She can't help being tall.

The phrase acknowledges involuntary behavior or circumstances beyond control.

Can't help but adds emphasis: I can't help but wonder what might have been.
