My boyfriend often jokes with me and says some hurtful things. Would you please tell me your opinion?

Jokes are jokes. If you break his heart because of a joke, won't it hurt your heart, too? If you are in love, there is really no need to care about these empty jokes unless he really does something to hurt you. Love should be sweet. Don't put these worries ahead of time, which will harm yourself and others. When the car gets there, it will find a way around the hill. Let go if you love, and don't wait until you lose it to regret not cherishing it.
