Which line from the text best supports the conclusion that Brutus intends to tell Portia about his plans?

"If this were true, then should I know this secret. / I grant I am a woman, but withal / A woman that Lord Brutus took to wife."
"I have made strong proof of my constancy, / Giving myself a voluntary wound / Here in the thigh. Can I bear that with patience, / And not my husband’s secrets?"
"O ye gods, / Render me worthy of this noble wife!"
"And by and by thy bosom shall partake / The secrets of my heart."
