How to respond to the boy's sentence "I can't help it if you think so"?

Then I can only learn from you like this.

When love encounters a cold period or a contradictory period, when the two sides walk together, they start all kinds of suspicions or quarrels; The woman will always have all kinds of suspicions about the man's indifference, while the boy will become more irritable and indifferent after getting used to the woman's suspicion. If they don't want to quarrel at all, they always end the conversation with "I can't help it if you think so."

If a man says this just to avoid the question, then the girl's best response can only be "then I can only learn from you in this way"; It doesn't matter if the other person thinks it's his own, I can only learn from him.
