Relationship advice

So I have been seeing this guy for a while now and honestly I think he's the one, he's so lovely and perfect for me and he says he feels the same way. I want our relationship to be official and for us to be a proper couple. So girls what's the cutest way to ask a guy to be your boyfriend considering I don't have a lot of money so can't be that grand of a gesture and normally it should be the guy asking but I really wanna do it 🙈🙈
