After breaking up, my boyfriend sent me a text message to respond. What does this mean?

From my perspective as a bystander, he should have given up on you.

Because when a man proposes to a woman, it must be a very serious matter after careful consideration, and you refuse on the grounds that you want to marry another man. His pride must be hurt. It is not a fun thing to lose your temper and quarrel when you are in love. If you just wanted to test his sincerity or something, I think you are stupid. How can you make such a big joke about your lifelong happiness?

If you feel unclear, you'd better ask him yourself. Of course, I want to wish you two can clear up the misunderstanding.
