Do I have to wear my engagement ring?
Is there a reason that you don't want to wear your engagement ring?
I'm afraid that I'll lose it.
I understand why you'd be nervous about wearing your engagement ring, because it's an important, expensive item. It's normal that you're afraid to lose it. I think you should wear it and be extra careful not to lose it, though.
It's actually not about being careful. I just don't like wearing it.
Don't you think your future spouse will be be upset if they realize that you aren't wearing the engagement ring? If you are having second thoughts about getting married, you should talk to them about it.
