It's better to listen to marriage at home. After all, your parents won't hurt your children.
Now that you are in the game, you feel that you have a good relationship with your boyfriend, but you can't see what will happen after marriage, but your parents and elders are different. They know that marriage and love are different, and they are more concerned about what problems they will encounter in the future. In other words, you feel that you have a good relationship with this man now, but this man is not suitable for marriage. Remember: marriage and love are two concepts. Actually, in my opinion, what does your family say? There is no way to talk to you about the whole family in the normal way. You may not accept that they are here, but this family means well. You should realize this.
My suggestion: listen to your family, don't let yourself regret listening to the old man more, suffer less and have limited youth.
