couldn't help

Had no choice

Couldn't help indicates inability to prevent or resist something—usually an action, feeling, or reaction.

The construction takes either a gerund or "but": I couldn't help laughing, She couldn't help but notice.

It implies the response was involuntary or irresistible: He couldn't help himself—he ate the whole cake.

Often serves as a mild apology for behavior.
