If he is short of money, you can discuss how to do a simple wedding. It doesn't have to be great, but at least it's a wedding. Getting married is a big deal. I think the wedding is an indispensable part of a person. Weddings witness your future.
But if he doesn't want to have a wedding just because he feels troublesome, I think you should have a good talk with him. Weddings are very important. If a woman gets married without a wedding, I think her life is missing. What woman didn't imagine herself walking on the red carpet in a white wedding dress when she dreamed at midnight? This is a very happy scene. After marriage, the two have been caring for each other and supporting each other. Both of them are the closest people to each other. I think this is very important. Some things we can choose not to do because of trouble, but some important things and procedures can't be saved. If your boyfriend doesn't want to do it because of this consideration, I think you are really pathetic. There is a saying that marriage is the grave of love. Although not every marriage is the grave of love, I think this sentence is not unreasonable. After marriage, strong feelings will fade after a long time. Daily necessities, mortgage, car loan, and busy work will all turn into pressure and put it on you. Life is dull, where there are so many vigorous events? Getting married is no longer a trivial matter. How long is a person's life? Don't even give up on this big thing?
Talk to him! If he can't understand you, then you don't have to accommodate him. One of you must give in, but I don't think as a woman, you can give in on this issue. Otherwise, after you get married, he will make you do more outrageous things, which you can't stand. However, he will not pity you. After all, you are willing to tolerate such a big thing as not having a wedding.
