Well, talk to him about what you want. Don't just expect him to read your mind. Part of being in an adult relationship, never mind a marriage, means opening your mouth and communicating to your partner.
But a proposal is just a formality. An engagement happens when two adults mutually decide to get engaged. That ought to happen BEFORE a bended knee proposal or a stupid ring.
The main problem here is that you're planning to marry a person without a job. Is he just not having luck finding something, or is he being lazy? Does he expect you to carry the family financially? If things work out where one person is the breadwinner and the other person works a low-paying or part-time job, or stays home to keep house/take care of kids, then that's fine ... and it doesn't matter if it's the wife or the husband who earns the money or stays home ... but that kind of lifestyle won't work if (a) you're both not on the same page about it, (b) if it only works out that way because he's too lazy to get a decent job or a job at all, and (c) if the budget just doesn't support only one person working.
Think twice about marrying a person with no job who expects you to do everything yourself. This has nothing to do with who proposes or who gets the rings ... it seems like he just expects you to carry the load while he does absolutely nothing. That's not sustainable for a marriage. You two are CLEARLY not on the same page about finances, spending, who works and who doesn't, who makes the decisions, etc. ... there's no point in a ring or a proposal if you cannot get on the same page about these very important, basic things. Work them out BEFORE you worry about who's buying a ring or who's getting down on one knee.
