What if my boyfriend ignores me because of a joke?

Girls are used to coax and hurt. Boys may not have experienced this stage, so they don't understand this truth. If he really cares about you, he won't ask you such a condition, and he won't ignore you because of it. The only reason is that he wants you. So you handled it correctly, indicating whether his feelings for you are true or false. But you are still young, it doesn't matter if you play, but you should pay attention to protect yourself. What others say about the rest of the feelings, it is better to do it yourself, and you will know how to deal with it next time. I hope it helps you.
