Engagement

So I'm 18 and a nursing student, and my boyfriend and I have together for quite some time now. Marriage is definitely in the cards and we've talked about tying the knot in a couple years, however, I really just want to start the engagement (I'm a rather assertive person). We've set up our new apartment for February and I'd really like to have a ring on my finger before then. So, how do we feel about me proposing to him? Any thoughts? Opinions? How I should go about it?
