It is not good for a woman to be three years older than a man. Is there such a saying?

Since you two love each other, you have to face everything. This is only the first step on the road to love. Now tell your parents that you have someone you love. They may be waiting for this day. I believe your choice is right, your girlfriend is the best, as long as it is the old man you love, how can you not like it?

Small idea: find a chance to let her go to your house for dinner with you. Just say she is a friend, and at the same time say that she is good and praise her a lot. Your parents must ask if you are interested in her, so just say so. "Yes, I like it, but how can your son be such a good object?" . Finally, don't forget to say "see if I have the blessing to make people fall in love with me, hehe". In this way, parents will think that she can accept her from another angle. It will be fine naturally in the future.
