What does it mean that your boyfriend who has been together for five years suddenly takes you shopping to see the house?

I want to marry you. I can't bear to spend money to save more money for you at one time. Otherwise, I'll show you the house ... although the clothes I bought for you are still not good ... your boyfriend is economical, although he is not so romantic ... cherish it. Really, landlord, don't miss it ... Of course, your conditions are very good, you can find a better boyfriend, except of course ... Hehe.
