There's nothing wrong to be a "大細路" but everything has its place and time. Depends on your age, maybe you should not put all your focus on "now", play now, spend $$ now. You may want to plan more for your future (both yours and hers). If you are still in school, maybe you should think about what you want to do after you finish school. If you are working already, maybe think about saving $$ to buy your own place, think about saving $$ for marriage. If you think your girlfriend will eventually marry you, don't you think she wants to have her own home with just you and her? Maybe think of advancing your career? At least show her that you have a plan in mind and you are doing something to go toward your goals whatever they are. If all you care is about now, no wonder she thinks there is not much of a 安全感 to be with you.
