I want to marry my lover

I am currently facing the confusion of getting married. I have been with my boyfriend for 5 years, and the relationship has been very good. He also loves me very much, but when the two families talked about getting married recently, my family did not agree with us. My parents have worked hard to support me for 20 years, and our family wants 100,000 gifts. They can’t get them out. My boyfriend said that these are all forms. Why should we give up our feelings for these 100,000? My parents disagreed, saying that we must consider practical issues when we get married. Don't say love when you have no money, it's hard to live a life. I want to give up, but I am not willing to give up. If I don’t give up, my parents always refuse this marriage. How should I do?
